“…Fig. 3 shows TAC spectra (for the 16 200 Pb* CN has been well studied through ER spin distribution using the fusion-evaporation reactions 16 O + 184 W and 19 F + 181 Ta [4,5] at IUAC. As the ER crosssection has been measured for 30 Si + 170 Er by Hinde et al [12] leading to the same CN, we chose to study the spin distribution for this reaction using the combined facility of HYRA and spin spectrometer to look for dissipation effects related to entrance channel mass asymmetry.…”

Abstract. The Hybrid Recoil mass Analyzer (HYRA) operated in gas-filled mode has recently been coupled with the TIFR 4 spin spectrometer at IUAC, New Delhi to carry out spin (or angular momentum) distribution of heavy residues from fusion-evaporation reactions and spin gated GDR measurements. The details of the combined facility, initial experiments on evaporation residue tagged -multiplicity and the extraction of average transmission efficiency of HYRA are elaborated.

“…Spin distribution and cross-section measurements are also sensitive probes for the investigation of the heavy ion induced fusion dynamics. Different authors have reported the existence of entrance channel effects on the fusion dynamics using spin distribution and cross section measurement as a probe [7,8]. With these motivations we have performed the evaporation residue (ER) cross-section (fusion crosssection) as well as ER spin distribution measurements for the asymmetric 16 …”

“…The deformation of one or both of the partners in a heavy-ion reaction is expected to differ drastically on the fusion cross-section at near barrier energies. The possible role of positive and negative hexadecapole deformation (β 4 ) effects in subbarrier fusion reactions have been investigated in the literature. The knowledge of nucleus-nucleus interaction potentials acts as an essential ingredient in the analysis of fusion-fission dynamics.…”
