Lifetimes of excited states of positive and negative parity ΔI = 2 bands of 106Cd have been measured using the Doppler Shift Attenuation Method (DSAM). The electric quadrupole reduced transition probability rates, B(E2), show a significant decreasing trend with increasing spin along with large observed ℑ(2)/B(E2) values. The experimental observations, interpreted in the framework of semiclassical particle-rotor model (SCM) calculations, suggest that these bands have the character of twin-shears type anti-magnetic rotational bands resulting from the coupling of g9/2 proton holes with h11/2, g9/2 and d5/2 neutron particles. Another negative-parity band in the same nucleus has been studied using SCM, which also interprets it to be an anti-magnetic rotational band. © The Author(s), under exclusive licence to Società Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature 2025.
MEASUREMENT OF EXCITATION FUNCTION IN THE 16 O + 107Ag SYSTEM AT ENERGIES ABOVE THE COULOMB BARRIER
(National Academy of Sciences of Ukraine, 2025) Diwanshu; Ajay Vinod Kumar; Bharti Rohila; Chetan Kumar Sharma; Subodh; P. S. Rawat; Amit Kumar Pandey; Kaushik T. Katre; Honey Arora; U. S.

The decay mechanism of the highly excited compound nucleus123Cs populated via fusion evaporation reaction of 16 O and107Ag is studied. De-excitation of the compound nucleus via evaporation of p, n, and α-particles leads to a population of several neutron-deficient residual nuclei. The excitation function for the16O +107Ag reaction has been determined experimentally in the energy range 71-80 MeV above the Coulomb barrier. The experimental results have been analyzed within the framework of statistical codes PACE4 and CASCADE. © The Author(s), 2025.
Study of nuclear structure in 122Ba from DCO Ratio and Polarization measurements
(Springer, 2025) Bharti Rohila; Ashok S.k. Kumar; Diwanshu; Chetan Kumar Sharma; Amit; Subodh; Honey Arora; Mehak Narula; Nabeel Salim; Paramasivan Arumugam; Md Anser; Hariprakash P. Sharma; Anand Pandey; S. K. Chamoli; Kaushik T. Katre; Yashraj; R. P. Singh; Sivaramakrishnan Muralithar
High-spin states in 122Ba have been investigated in the 93Nb(32S, p2n) reaction by in-beam γ-ray spectroscopy. Spin and parity have been determined for few bands using the DCO ratio and polarization measurements. The cranked shell model calculations have been performed to reproduce the band crossing frequencies and alignment gain in order to assign the configuration. © The Author(s), under exclusive licence to Società Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature 2025.
