High spin states of, 130,131Ba have been investigated via fusion evaporation reactions 122Sn (13C,4n)131Ba and 122Sn(13C, 5n)130Ba at Ebeam = 65MeV. The level schemes of 130,131Ba have been extended by placing several new γ transitions. A few interband transitions connecting two negative-parity bands, which are the experimental fingerprints of signature partners, have been established in 130Ba. Spin and parity of a side band have been assigned in 131Ba and this dipole band is proposed to have a three-quasiparticle configuration, vh11/2 ⊗ πh11/2⊗ πg7/2. The observed band structures and nuclear shape evolution as a function of the angular momentum have been discussed in the light of Total-Routhian-Surface calculations. © Società Italiana di Fisica/Springer-Verlag 2014.
Polarization measurements and high spin structure in 131Ba
(2013) Navneet Kaur; A. Kumar; G. Mukherjee; Amandeep Singh; Varinderjit Singh; Rohit Sandal; Rajbir Kaur; B.R. Behera; K.P. Singh; G. Singh; H.P. Sharma; Suresh Kumar; M.K. Raja; P.V. Madhusudhan Rao; S. Muralithar; R.P. Singh; Rakesh Kumar; N. Madhavan; C.R. Praharaj; Z. Naik
The high spin states of 131Ba have been populated in the fusion evaporation reaction 122Sn(13C,4n)131Ba at Ebeam=65MeV. The γ transitions belonging to various band structures were detected using an array of fifteen Clover Germanium detectors. Some of new transitions have been placed in high spin states. Spin and parity for a band has been calculated for first time in 131Ba. The said band is interpreted in term of multi-quasiparticle configurations, based on Total Rothian Surfaces (TRS) calculations. © 2013 AIP Publishing LLC.
