Competing coexistence models in medium-mass nuclei

Competing coexistence models in medium-mass nuclei Simple phenomenological two-state coexistence models have previously been developed to describe the ground state and some low-lying 0 + ’ excited state in isotopic chains of even-even medium-mass nuclei. Specifically, these models allow for mixing between a basis ground state and a basis 0 + intruder state to form the wave functions for the physical ground state and 0 + ’ excited state. The amount of data accounted for by these models is amazing, considering their simplicity. However, these two-state phenomenological models contain inconsistencies that have previously been overlooked. We point out some of these inconsistencies and emphasize that they can be removed by a slight generalization of the two-state coexistence model, without destroying agreement between data and model predictions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review C American Physical Society (APS)

Abstract

Simple phenomenological two-state coexistence models have previously been developed to describe the ground state and some low-lying 0 + ’ excited state in isotopic chains of even-even medium-mass nuclei. Specifically, these models allow for mixing between a basis ground state and a basis 0 + intruder state to form the wave functions for the physical ground state and 0 + ’ excited state. The amount of data accounted for by these models is amazing, considering their simplicity. However, these two-state phenomenological models contain inconsistencies that have previously been overlooked. We point out some of these inconsistencies and emphasize that they can be removed by a slight generalization of the two-state coexistence model, without destroying agreement between data and model predictions.
