Low-lying levels in the odd-mass isotopes of antimony

Abstract

The core-particle-coupling model in which the motion of an unpaired particle is coupled to an oscillating field is used to calculate the properties of the low-energy spectra of the odd-mass isotopes of antimony. This model, despite its simplicity, provides a reasonably correct description of many observed data, e.g. energy levels, spectroscopic factors and transition rates. It was stipulated that the description of the regular trends observed in the seven isotopes ranging from A = 113 to A = 125 should be obtained with a minimum of free parameters.
