“…In 131 Xe, both calculations predict a continuous decrease of occupation in the neutron intruder orbital νh 11/2 until it reaches The proton occupancy of the πh 11/2 orbital in 131 Xe is predicted to be N π ≈ 0. . This finding agrees with previous investigations within the framework of the cranked shell model where an alignment of two h 11/2 protons was proposed recently [16]. Supported by the observation in 129 Xe, the proton h 11/2 configuration in 131 Xe has a perturbative but decisive role for the description of the structure of alignment states.…”

“…Based on the experimental data, a J π = 27/2 6. Evolution of excited states in the negative-parity band along (a) the odd-mass N = 77 isotones from Z = 50 to Z = 64 [72][73][74][75][76][77] and along (b) the odd-mass Z = 54 isotopes from N = 69 to N = 77 [16,43,78]. Newly discovered states in 131 Xe are marked with thick lines.…”

“…In 129 Xe a pronounced upbend is found. Huang et al [16] explained the upbend by an alignment of two h 11/2 protons according to CSM calculations [16]. The negative-parity band in 131 Xe exhibits a large increase of approx.…”

“…In the majority of cases, the theoretical investigations of such systems were carried out by means of the interacting boson model (IBM) [9,12,13], mean-field methods [2,14], or the cranked shell model (CSM) [15,16]. However, Xe isotopes have come within reach of advanced untruncated shell-model calculations, providing stringent tests of the predictive power and suitability of various nuclear potentials and models based on modern effective interactions in this region.…”

“…In 2016, Huang et al [16] extended the level scheme of the negative-parity ground-state band (α = −1/2) up to the J π = 35/2 − 1 state at 5194 keV utilizing a 9 Be-induced fusionevaporation reaction on a 124 Sn target at a beam energy of 36 MeV. The Nilsson configuration for the band was determined to be νh 11/2 [505] 11/2.…”

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

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.
