[en] The positive parity decoupled bands in odd-odd nuclei ¹²⁶Pr, ¹²⁸Pr, ¹³⁰Pr, ¹³²Pr, ¹³⁴Pr and ¹³⁴Pm have been investigated using the particle rotor model. The aim was to find the valence proton-neutron configuration for the decoupled bands by comparing the calculated energy levels and transition probabilities with experimental results

[en] Fusion, transfer and breakup reactions and their relative importance on reaction mechanism involving weakly bound projectiles is a topic of intense current interest. In this context, several experimental studies have been performed over the years utilizing projectiles of both stable and unstable weakly bound nuclei. The systematic of inclusive, reaction and total fusion cross sections with various projectiles have been highlighted in these studies. However, the neutron transfer cross sections with these projectiles have not received much attention. ⁹Be, being a cluster structure of α + α + n, with a breakup threshold of 1.67 MeV, the neutron may play major role in reaction dynamics. In the recent paper of ⁹Be + ¹⁸⁷Re system, complete (CF), incomplete fusion (ICF) and neutron transfer cross sections have been measured. In the present work we have estimated the neutron transfer cross sections from Coupled Channel Calculations and also deduced the relative importance of CF, ICF and neutron transfer with respect to the reaction cross sections

[en] Here we present the results of our experimental investigation of ¹²⁶Te populated via incomplete fusion α-channel and ¹²⁹Xe populated via compound nuclear fusion 4n-channel in the same experiment. A γ - γ coincidence experiment with four HPGe clover detectors was performed using a target of ¹²⁴Sn and ⁹Be beam of energy 46 MeV delivered by the Pelletron accelerator at Tata Institute of Fundamental Research, Mumbai

[en] In the literature, the phenomenon of signature inversion in nuclei has been explained using many different arguments, e.g., triaxial nuclear deformation, neutron-proton interaction. The signature splitting and signature inversion in the most intensely populated negative parity band of ¹²⁶I has been observed. Here the results in terms of cranking model and particle-rotor model have been presented and discussed

[en] Many nuclei in the mass region ∼ 130 e.g. ¹³⁸Gd, ¹³⁶Sm, ¹³⁴Nd, ¹³²Ce, ¹³⁰Ba, ¹²⁸Xe have been found in the literature to have K-isomers. The nucleus ¹²⁶Te has been chosen for studying K-isomerism. This nucleus is expected to have γ - soft behavior and may exhibit K-isomerism as predicted by Xu et al. The energy states up to 10 h have been identified in ¹²⁶Te. The plan was to build the level scheme first and then look for the isomer, if there is any. Here the experimental result on the excited states of ¹²⁶Te have been presented

[en] The phenomena of chirality and decoupling were the main motivation towards studying the odd-odd nucleus ¹²⁶I. So far, in the literature the nucleus ¹²⁶I was produced using the reaction ¹²⁶Te (p, n)¹²⁶I and very low lying states have been reported. Here we present the identification of the gamma transitions belonging to ¹²⁶I and the population of its high spin states with very good cross-section
