“…The inclusive measurements, in spite of their simplicity, may also be useful in the study of clustering phenomena. For example, in our recent paper [10] the obtained large value of the deformation parameter might be considered as the confirmation of the cluster structure of the low-lying states of 9 Be. However, the inclusive measurement did not allow us to give unambiguous preference to one of the possible configurations, e.g.…”

The study of inelastic scattering and multi-nucleon transfer reactions was performed by bombarding a 9 Be target with a 3 He beam at the incident energy of 30 MeV. Angular distributions for 9 Be(3 He, 3 He) 9 Be, 9 Be(3 He, 4 He) 8 Be, 9 Be(3 He, 7 Be) 5 He, 9 Be(3 He, 6 Li) 6 Li and 9 Be(3 He, 7 Li) 5 Li reaction channels were measured. Experimental angular distributions for the corresponding ground states (g.s.) were analyzed within the framework of the optical model, the coupled-channel approach and the distorted-wave Born approximation. Cross sections for channels leading to unbound 5 Heg.s., 5 Lig.s. and 8 Be systems were obtained from singles measurements where the relationship between the energy and the scattering angle of the observed stable ejectile was constrained by two-body kinematics. Information on the cluster structure of 9 Be was obtained from the transfer channels. It was concluded that cluster transfer was an important mechanism in the investigated nuclear reaction channels. In the present work an attempt was made to estimate the relative strengths of the interesting (n + 8 Be) and (α + 5 He) cluster configurations in 9 Be. The contributions of different exit channels have been determined confirming that the (α + 5 He) configuration plays an important role. The configuration of 9 Be consisting of two bound helium clusters (3 He + 6 He) is significantly suppressed, whereas the two-body configurations (n + 8 Be) and (α + 5 He) including unbound 8 Be and 5 He are found more probable.

“…(E < 10 MeV/nucleon), phenomena like fusion, fission, elastic and inelastic scattering cannot be studied without the knowledge of nucleus-nucleus potential. Even at intermediate energies, an accurate knowledge of the total interaction potential is necessary to study various observables like multifragmentation [16][17][18], collective flow [19][20][21] etc.…”

Abstract. We develop a new technique to calculate fusion barrier heights of any fixed target reaction series. We calculate the barrier heights for the fusion reactions of 119 Sn and 197 Au targets using this technique. This technique is simple and very useful for estimating the fusion barrier heights for those reactions for which empirical values are not available. A formula is derived by performing theoretical calculations using different versions of proximity potential. Using this formula, we can predict the barrier height for the fusion reaction of any projectile with 119 Sn or 197 Au target using the empirical barrier height for the fusion reaction of same projectile with 62 Ni target. In order to check the accuracy of this technique, the fusion parameters calculated by this new technique are compared with the fusion parameters calculated by using parameterized formulae presented in a systematic study conducted by using double folding model.

“…One has also studied multifragmentation and other properties at the balance point [9]. Recently, we reproduced the mass dependence of balance energy for more wider range using 20% constant reduction of the cross-section with SMD EoS [10] using isospin quantum molecular dynamics (IQMD) model. At the same time, directed flow is also found to be affected by the neutron content of the colliding pair.…”

We study the relative role of density-dependent reduction and constant reduction of the cross-section on the mass dependence of balance energy throughout the mass range for two isobaric series corresponding to different neutron to proton contents using isospin-dependent quantum molecular dynamics model. Our study indicates that mass-dependent analysis of balance energy for semi-central collisions is almost insensitive to the choice of reduction in the cross-section. This insensitivity remains preserved for static as well as momentum-dependent soft equation of state.
