| 1 | Revisiting band structures in^(118)Xe nucleus via in-beamγ-ray spectroscopy显示文摘The neutron deficient Xe nuclei with A≈120 are predicted to have strong octupole correlation at low spins.In the present study,an attempt was made to improve upon the level scheme and also to examine the signatures of octupole correlation in^(118)xe via high spin γ-ray spectroscopy.High spin states in^(118)Xe have been populated via the^(93)Nb(^(28)Si,p2n)^(118)Xe fusion-evaporation reaction at a beam energy of 115 MeV provided by the 15 UD pelletron accelerator facility at IUAC,New Delhi.In the experiment,seven newγ-transitions have been found and placed appropriately in the level scheme.A theoretical study using the triaxial projected shell model(TPSM)approach suggests that the first bandcrossing is due to the alignment of two neutrons,and a parallel band tracking the yrast configuration is the γ-band built on the two-quasiparticle state.Enhanced E1 transition rates measured between opposite parity bands involving vh_(11/2)and vd_(5/2)orbitals having△j=△l=3 indicate the presence of octupole correlation in this nucleus. | A.Pandey R.Bhushan A.Rohilla C.Majumder H.P.Sharma S.Chakraborty R.P.Singh S.Muralithar Yashraj K.Katre B.Rohila Subodh A.Kumar I.M.Govil S.Jehangir N.Rather G.H.Bhati A.A.Wani J.A.Sheikh S.K.Chamoli | 2023 | Chinese Physics C2023，47，8： | 0 |
