Conclusive evidence of magnetic rotational band in 57Fe: Extending the shears mechanism to the fp shell orbital

S. K. Basu, Gopal Mukherjee, S. Rajbanshi, Y. Utsuno et autres

A Magnetic Rotational (MR) band in 57 Fe nucleus has been newly identified and established from the decreasing behaviour of the experimental electric dipole transition probabilities, B(M1), determined from the measured lifetimes of the states. This becomes the first nucleus in the …

Coexistence of single-particle and collective states in Sb 116

Shabir Dar, Soumik Bhattacharya, Sarmishtha Bhattacharyya, G. H. Bhat et autres

Single-particle and collective excitations in $^{116}\mathrm{Sb}$ are studied using the reaction $^{115}\mathrm{In}(\ensuremath{\alpha},3n)^{116}\mathrm{Sb}$ at a beam energy of 40 MeV and investigated using $\ensuremath{\gamma}$-ray spectroscopic techniques. The existing level scheme is extended with the observation of several new transitions. The previously known band …

Direct Evidence of Topological Dirac Fermions in a Low Carrier Density Correlated 5d Oxide

Premakumar Yanda, Jorge Cardenas-Gamboa, Ding Pei, François Bertran et autres

The convergence of crystalline symmetry, spin-orbit coupling (SOC), and electron correlations provides a powerful route to realizing quantum states with nontrivial topology and exotic transport responses. Here, the discovery of a topological semimetallic state is reported in BiRe$_2$O$_6$, a newly identified 5d …

Spectroscopic study of V 50

Arkadip Bera, Abhijit Bisoi, Y. Sapkota, Rozina Rahaman et autres

High-spin positive parity states of $^{50}\mathrm{V}$, populated through the $^{48}\mathrm{Ti}(^{4}\mathrm{He},np)^{50}\mathrm{V}$ reaction with a 48 MeV $\ensuremath{\alpha}$ beam, have been studied using the Indian National Gamma Array (INGA) facility. A few new levels and $\ensuremath{\gamma}$-ray transitions have been added to the level scheme …

Yrast and nonyrast states in Te126

Atreyee Dey, A. K. Singh, A. Basu, Somnath Nag et autres

The yrast and nonyrast states of $^{126}\mathrm{Te}$ were populated in a fusion-evaporation reaction using a target of $^{124}\mathrm{Sn}$ and $\ensuremath{\alpha}$ beam at 31 MeV energy. All the $\ensuremath{\gamma}\text{\ensuremath{-}}\ensuremath{\gamma}$ coincidences were recorded using the Indian National Gamma Array at the Variable Energy Cyclotron …

Existance of octupole correlation in 116Sn

Prithwijita Ray, H. Pai, S. Chakraborty, Anindya A. Mukherjee et autres

The negative parity states in 116Sn have been investigated in terms of octupole correlation. The same is probed by using the Indian National Gamma Array (INGA) facility at Variable Energy Cyclotron Centre, Kolkata using the reaction, 114Cd(α,2n) 116Sn at 34 MeV energy. …

Search for the origin of wobbling motion in the A≈130 region: The case of Xe131

S. Chakraborty, S. Bhattacharyya, Rupak Banik, Soumik Bhattacharya et autres

In-beam $\ensuremath{\gamma}$-ray spectroscopy of $^{131}\mathrm{Xe}$ was carried out to study the structure of the intruder $\ensuremath{\nu}{h}_{11/2}$ band. Excited states were populated via an $\ensuremath{\alpha}$-induced fusion-evaporation reaction at ${E}_{\ensuremath{\alpha}}=38\phantom{\rule{4pt}{0ex}}\mathrm{MeV}$. Inspection of $\ensuremath{\gamma}\ensuremath{\gamma}$-coincidence data resulted in the identification of a new rotational sequence. Based …

Single-particle configurations of low- and medium-spin states in Cu63

S. Chatterjee, B. Mondal, S. Samanta, S. Das et autres

The excitation scheme of the $^{63}\mathrm{Cu}$ nucleus has been probed following its population in a light-ion induced fusion-evaporation reaction and using an array of Compton suppressed HPGe clover detectors as the detection system. Apart from ascribing $\ensuremath{\gamma}$-ray transitions to the level scheme …
