“…Previous experiments on 131 Xe focused primarily on low-spin excitations observed after β decay [20][21][22][23], (γ,γ ) reactions [24][25][26], or Coulomb excitation [27]. Like several odd-mass 50 Z,N 82 nuclei, 131 Xe exhibits a long-lived J π = 11/2 − 1 isomer.…”

The transitional nucleus 131 Xe is investigated after multinucleon transfer in the 136 Xe + 208 Pb and 136 Xe + 238 U reactions employing the high-resolution Advanced γ -Tracking Array (AGATA) coupled to the magnetic spectrometer PRISMA at the Laboratori Nazionali di Legnaro, Italy, and as an elusive reaction product in the fusion-evaporation reaction 124 Sn( 11 B,p3n) 131 Xe employing the High-efficiency Observatory for γ -Ray Unique Spectroscopy (HORUS) γ -ray array coupled to a double-sided silicon strip detector at the University of Cologne, Germany. The level scheme of 131 Xe is extended to 5 MeV. A pronounced backbending is observed at hω ≈ 0.4 MeV along the negative-parity one-quasiparticle νh 11/2 (α = −1/2) band. The results are compared to the high-spin systematics of the Z = 54 isotopes and the N = 77 isotones. Large-scale shell-model calculations employing the PQM130, SN100PN, GCN50:82, SN100-KTH, and a realistic effective interaction reproduce the experimental findings and provide guidance to elucidate the structure of the high-spin states. Further calculations in 129−132 Xe provide insight into the changing nuclear structure along the Xe chain towards the N = 82 shell

“…Population of 131 Xe is difficult due to lack of stable target-projectile combinations. Previous spectroscopic studies on this nuclei were carried out from decay spectroscopy [6,7], Coulomb excitations [8], (α , 3n) [1] and (α , n) [9] measurements. But these studies are limited by the detection system used.…”

High and medium spin structures of 130,131Xe have been studied using α-induced fusion-evaporation reaction and the Indian National Gamma Array (INGA) coupled with a digital data acquisition system. Various new band structures and near yrast levels of 131Xe have been established. The multipolarities of the observed transitions have been assigned on the basis of the DCO ratios and the polarization asymmetry measurements. Band structures based on 1-quasi-particle (qp), 3-qp configurations have been observed. A new Magnetic Rotational (MR) band based on 5-qp configuration has also been established in 131Xe. The MR band has been interpreted in terms of shears mechanism with principal axis cranking (SPAC) calculations. Shell Model calculations are carried out to describe the non yrast states of 131Xe above the 11/2− isomer. New excited states have also been identified in 130Xe, produced in the same reaction.
