At a fundamental level, the interactions between protons and protons, protons and neutrons, and neutrons and neutrons are not identical. Such isospin nonconserving interactions emerge when comparing the excitation energy of analog states in T=1 triplet nuclei. Here, we extend such an analysis to the A=78, T=1 triplet system-the heaviest system for which such complete data exists-and find strong disagreement with contemporary theory. This was achieved by pioneering the technique of recoil-β-β tagging to identify excited states in ^{78}Zr. We also established a ^{78}Zr half-life of 25_{-8}^{+17} ms and extended the T=1 band in ^{78}Y to J^{π}=(10^{+}).

Abstract The spin-distributions of different reaction products populated via x n and α/2αx n channels in C 12 + Tm 169 system have been measured at E lab ≈ 6, 7 and 7.5 MeV A−1 to disentangle complete and incomplete fusion events. Particle (p, α)-γ-coincidences were recorded to identify evaporation residues channel-by-channel. The spin-distributions of fusion evaporation and direct-α-emitting channels are found to be distinct corroborating the involvement of entirely different reaction dynamics in their production, respectively termed as complete (CF) and incomplete fusion (ICF). The values of mean input angular momenta, obtained from the analysis of the spin-distributions, involved in ICF-α/2α xn channels are estimated to be larger than that observed in CF-xn/α xn channels. For ICF-α/2αxn channels, the multiplicity of fast-α particle emission increases with the magnitude of input angular momentum imparted into the system. The CF residues display a population of broad spin range while the ICF residues are confined to a narrow spin range generally localized in the higher spin states. Findings of the present work conclusively demonstrate the possibility to populate high spin states in final reaction products using ICF, which are otherwise not accessible. Further, an attempt has been made to study the variation of input angular momentum with the choice of different entrance-channel parameters. It has been observed that the value of input angular momentum involved in ICF-α/2α xn channels increases with the deformation and entrance-channel mass-asymmetry parameter, indicating strong entrance-channel dependence of ICF dynamics.

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)].

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.

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.
