Further examination of a possible vibrational-rotational index

Abstract

For other, mostly non-coexistence nuclei, I have examined a dimensionless ratio of E2 strengths that has been demonstrated to display a double-peaked frequency distribution for coexistence nuclei, with a void of points near R = 0.20. Results indicate that the lower peak remains, as does a deep minimum near R = 0.20, but that ratios above R = 0.20 are more widely spread for nuclei not known to exhibit coexistence.
