Fusion excitation function of $^{35}$Cl + $^{130}$Te system is measured in the energy range around the Coulomb barrier and analyzed in the framework of the coupled-channels approach. The role of projectile deformation, nuclear structure, and the couplings of inelastic excitations and positive Q$-$value neutron transfer channels in sub-barrier fusion are investigated through the comparison of reduced fusion excitation functions of $^{35,37}$Cl +$^{130}$Te systems. The reduced fusion excitation function of $^{35}$Cl + $^{130}$Te system shows substantial enhancement over $^{37}$Cl + $^{130}$Te system in sub-barrier energy region which is attributed to the presence of positive Q-value neutron transfer channels in $^{35}$Cl + $^{130}$Te system. Findings of this work strongly suggest the importance of +2$n$ - transfer coupling in sub-barrier fusion apart from the simple inclusion of inelastic excitations of interacting partners, and are in stark contrast with the results presented by Kohley \\textit{et al.}, [Phys. Rev. Lett. 107, 202701 (2011)]. - Study of Mass-Asymmetric Fission of <sup>180,190</sup>Hg Formed in the <sup>36</sup>Ar + <sup>144,154</sup>Sm Reactions

t—The mass–energy distributions of fission fragments of excited 180,190Hg nuclei formed in 36Ar + 144,154Sm reactions are measured at incident 36Ar energies of 158, 181, and 222 MeV using the double-arm time-of-flight spectrometer CORSET. The asymmetric fission of 180,190Hg with the most probable masses of light and heavy fragments of 79 and 101 amu, and 84 and 106 amu, respectively, is observed in mass distributions of 180,190Hg at energies of excitation of up to 75 MeV. Two components manifesting the symmetric and asymmetric fission modes are observed in the kinetic energy distributions. - Quasielastic scattering measurements in the Si 28 + Nd 142,150 systems

Abstract Thin 130Te target foils of thickness 139– 260 μ g /cm 2 have been prepared on 12C backing using resistive evaporation technique for sub-barrier fusion studies in heavy-ion induced nuclear reactions. The deposition thickness of both 12C and 130Te has been measured using profilometer, and the thickness of a few target foils has been measured using α -transmission method. Target foils fabricated in the present work have been characterized using the Rutherford Backscattering Spectrometry (RBS), Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Spectroscopy (EDXS) for impurity and to estimate the thickness. 130Te is known to be brittle with the low melting point, and it quickly degrades if bombarded with energetic heavy-ion beams. In the present work, 130Te target foils fabricated on carbon backing were bombarded with 70 MeV 32S and 114–155 MeV 35 , 37 Cl beams to vet the stability of the targets. It has been observed that 130Te target foils fabricated on 12C backing survived the bombardment with energetic 32S, and 35 , 37 Cl beams without any degradation for the entire duration of sub-barrier fusion measurement at different energies. - Entrance channel effects on fission fragment mass distribution in <sup>12</sup> C+ <sup>169</sup> Tm system

Abstract In the present work, channel-by-channel excitation functions of different evaporation residues populated via complete and/or incomplete fusion in C 12 + 169 Tm system have been measured for an energy range E lab ≈ 53 – 90 MeV , using recoil-catcher activation technique followed by off-line γ-spectroscopy. Experimentally measured excitation functions have been analysed in the framework of statistical model code pace . To probe the effect of entrance-channel parameters on the onset and strength of incomplete fusion, relative contributions of complete and incomplete fusion have been deduced from the analysis of experimentally measured excitation functions. The percentage fraction of incomplete fusion deduced from the analysis of excitation functions has been studied in terms of incident energy, entrance-channel mass-asymmetry, ground state alpha-Q-value, neutron skin thickness of target nuclei, and nuclear potential parameters. It has been found that incomplete fusion start competing with complete fusion even at slightly above barrier energies where complete fusion is assumed to the sole contributor. The probability of incomplete fusion increases with incident energy, entrance channel mass-asymmetry, large negative ground state alpha-Q-value, neutron skin thickness, and nuclear potential parameters for individual projectiles. - Sub-barrier fusion in the Cl 37 + Te 130 system

The reaction mechanism of deep-inelastic multinucleon transfer processes in the $^{16}$O+$^{27}$Al reaction at an incident $^{16}$O energy ($E_{\\rm lab}=134$~MeV) substantially above the Coulomb barrier has been studied both experimentally and theoretically. Elastic-scattering angular distribution, total kinetic energy loss spectra and angular distributions for various transfer channels have been measured. The $Q$-value- and angle-integrated isotope production cross sections have been deduced. To obtain deeper insight into the underlying reaction mechanism, we have carried out a detailed analysis based on the time-dependent Hartree-Fock (TDHF) theory. A recently developed method, TDHF+GEMINI, is applied to evaluate production cross sections for secondary products. From a comparison between the experimental and theoretical cross sections, we find that the theory qualitatively reproduces the experimental data. Significant effects of secondary light-particle emissions are demonstrated. Possible interplay between fusion-fission, deep-inelastic, multinucleon transfer, and particle evaporation processes are discussed. - Entrance channel effect on incomplete fusion

In the present work, low energy incomplete fusion (ICF) in which only a part of projectile fuses with target nucleus has been investigated in terms of various entrance channel parameters. The ICF strength function has been extracted from the analysis of experimental excitation functions (EFs) measured for different projectile-target combinations from near- to well above- barrier energies in 12 C,16 O(from 1.02Vb to 1.64Vb )+169 Tm systems. Experimental EFs have been analysed in the framework statistical model code PACE4 based on the idea of equilibrated compound nucleus decay. It has been found that the value of ICF fraction (FICF ) increases with incident projectile energy. A substantial fraction of ICF (FICF ≈ 7 %) has been accounted even at energy as low as ≈ 7.5% above the barrier (at relative velocity ν rel ≈0.027) in 12 C+169 Tm system, and FICF ≈ 10 % at ν rel ≈0.014 in 16 O+169 Tm system. The probability of ICF is discussed in light of the Morgenstern’s mass-asymmetry systematics. The value of FICF for 16 O+169 Tm systems is found to be 18.3 % higher than that observed for 12 C+169 Tm systems. Present results together with the re-analysis of existing data for nearby systems conclusively demonstrate strong competition of ICF with CF even at slightly above barrier energies, and strong projectile dependence that seems to supplement the Morgenstern’s systematics.
