- Abstract
Rotational bands built on positive parity s 1 / 2 , d 3 / 2 , and g 7 / 2 valence neutron orbitals in 127 Xe have been investigated via in-beam γ ray spectroscopy. Excited states belonging to these one-quasineutron bands were populated via 122 Sn (9 Be , 4n γ ) fusion-evaporation reaction at a beam energy of 48 MeV. The level scheme has been updated by extending the low-lying rotational bands up to higher spin states, as well as, by assigning the spin/parity of the constituting energy levels. Signature splitting of low-j ν s 1 / 2 , ν d 3 / 2 and high-j ν g 7 / 2 bands have been discussed in comparison to the neighbouring nuclei. Theoretical Modified Particle Rotor Model (MPRM) calculations have been carried out in order to study the microscopic structure of these bands.
