Abstract
The distribution of reduced transition probabilities in Na-22 has been studied using the shell model. B(M1) and B(E2) values have been calcu lated for transitions among the first 25 states with each spin from J= 0 to J=8, positive parity, and isospins T = 0 or T = 1. No dependence on spin, isospin, electromagnetic character, or excitation energy was found. The results were consistent with a chi(2)(v) distribution with v = 1, suggesting that Na-22 is chaotic in the energy range studied.
