[en] The nucleus ⁷Li is a very interesting light nucleus owing to its low breakup threshold, prominent cluster structure of α and t inside, and its observed abundancy. DWBA calculations for ⁷Li breakup has been carried out and the results are consistent with the data except for a reduction factor indicating possible channel coupling effect

[en] Quasifission reactions are binary processes exhibiting some characteristics of fusion-fission events such as full relaxation of kinetic energy and considerable transfer of mass between two fragments. With the object to study this type of phenomena an experiment is undertaken to measure angular anisotropy and mass distribution using ²⁰⁹Bi spherical and ¹⁸¹Ta deformed target

[en] The ALICE dimuon experiment is intended to look for the muon pairs coming from various resonance decays such as J/ψ, τ etc. The suppression of these resonances is one of the potential probes of the Quark Gluon Plasma (QGP) expected to be formed in ultra relativistic Pb- Pb collisions. If this is true, then the suppression of cc-bar and bb-bar resonances should be reflected in the invariant mass distribution of muon pairs coming from these resonance decays

[en] A large hadron collider experiment (ALICE) is intended to look for quark gluon plasma (QGP) expected to be formed in ultra-relativistic heavy ion collisions (URHIC). In the present work different characteristics for the bending plane of CPC with the new generation (1.2-3.1 version) of MANAS chip are evaluated

[en] Fission fragment angular distributions of heavy-ion induced fission in actinide nuclei at near-barrier energies show anomalous fragment anisotropies. At above barrier energies entrance channel dependence is a probable cause and explanation in terms of pre-equilibrium fission and the critical mass asymmetry parameter (Businaro-Gallone) has been tried. Target deformation and ground state spin also seem to influence the measured anisotropy. To understand the extent of importance of some or all of these features, we performed a set of experiments where (i) entrance channel dependence (ii) mass asymmetry on the two sides of Businaro-Gallone and (iii) different ground state spins are present. The channels chosen are ¹⁴ N+ ²³² Th and ¹¹ B+ ²³⁵ U. Experiments were done using the Pelletron accelerators at NSC, New Delhi and BARC-TIFR, Bombay. Compound nucleus populated in both cases is ²⁴⁶ Bk. ²³² Th has ground state spin zero and ²³⁵ U has spin 7/2. Fragment anisotropies have been measured from 10-15 % above barrier to 10 % below barrier at similar excitation energy (around 40 MeV to 58 MeV). The mean square angular momentum is matched at least at one energy. Results indicate that when both excitation energy and angular momentum are matched, there are differences in the measured values of fission anisotropies. This implies entrance channel dependence consistent with the expectation of pre-equilibrium fission model. (authors)
