| 1 | Systematic study of odd-mass^151-161Pm and^154,156Pm isotopes using projected shell model显示文摘Inspired by the availability of recent experimental as well as theoretical data on the energy levels of odd-mass^151-161Pm and odd-odd^154,156Pm,we applied the theoretical framework of the projected shell model to further understand the nuclear structure of these nuclei.The calculations closely reproduced the experimental data reported for the yrast bands of these isotopes by assuming an axial(prolate)deformation of^0.3.Other properties along the yrast line,such as transition energies and transition probabilities,have also been discussed.Band diagrams are plotted to understand their intrinsic multi-quasiparticle structure,which turn out to be dominated by 1-quasiparticle bands for the odd-mass Pm isotopes and 2-quasiparticle bands for the doubly-odd Pm isotopes under study.The present study not only confirms the recently reported experimental/theoretical data,but also extends the already available information on the energy levels and adds new information regarding the reduced transition probabilities. | Veerta Rani Preeti Verma Suram Singh Manvi Rajput Arun Bharti G.H.Bhat J.A.Sheikh | 2020 | Chinese Physics C2020，44，9： | 0 |
| 2 | Microscopic study of electromagnetic properties and band spectra of neutron deficient 133,135,137Sm显示文摘A microscopic high spin study of neutron deficient and normally deformed 133,135,137Sm has been carried out in projected shell model framework.The theoretical results have been obtained for the spins,parities and energy values of yrast and excited bands.Besides this,the band spectra,band head energies,moment of inertia and electromagnetic transition strengths are also Predicted in these isotoPes.The calculations successfully give a deeper understanding of the mechanism of the formation of yrast and excited bands from the single and multi-quasi particle configurations.The results on moment of inertia predict an alignment of a pair of protons in the proton(1 h11/2)^2 orbitals in the yrast ground state bands of 133-137Sm due to the crossing of one quasiparticle bands by multi-quasiparticle bands at higher spins.The discussion in the present work is based on the deformed single particle scheme.Any future experimental confirmation or refutation of our predictions will be a valuable information which can help to understand the deformed single particle structure in these odd mass neutron deficient 133-137Sm. | Rakesh K.Pandit R.K.Bhat Rani Devi S.K.Khosa G.H.Bhat J.A.Sheikh | 2019 | Chinese Physics C2019，43，12： | 0 |
| 3 | Evolution of intrinsic nuclear structure in medium mass even-even Xenon isotopes from a microscopic perspective显示文摘In this study,the multi-quasiparticle triaxial projected shell model(TPSM)is applied to investigateγ-vibrational bands in transitional nuclei of 118-128Xe.We report that each triaxial intrinsic state has aγ-band built on it.The TPSM approach is evaluated by the comparison of TPSM results with available experimental data,which shows a satisfactory agreement.The energy ratios,B(E2)transition rates,and signature splitting of theγ-vibrational band are calculated. | Surbhi Gupta Ridham Bakshi Suram Singh Arun Bharti G.H.Bhat J.A.Sheikh | 2020 | Chinese Physics C2020，44，7： | 0 |
