Identification of excited states in Te5552107

Excited states in the extremely neutron-deficient nucleus Te107 have been identified from two separate experiments using recoil-decay tagging technique. Two connected structures were observed on basis of γγ-coincidence relations and tentatively assigned as built mixed-parentage νg7/2d5/2 νh11/2 intruder configurations. The compared with large-scale shell-model calculations total Routhian surface calculations. Collective behavior was discovered to persist band which highlights shape-polarizing effect a single valence neutron occupying h11/2 orbit N=50 shell closure is approached.1 MoreReceived 31 August 2021Accepted 22 November 2021DOI:https://doi.org/10.1103/PhysRevC.104.064305Published by American Physical Society under terms Creative Commons Attribution 4.0 International license.
