Coulomb Excitation of Sb, Cs, and Ba

Abstract

Coulomb excitation of several nuclei in the region between $A=123\mathrm{} \mathrm{and} 137$ has resulted in observation of the following gamma rays: ${\mathrm{Sb}}^{123}$, 161 and 376 kev; ${\mathrm{Cs}}^{133}$, 82, 163, 302, and 385 kev; ${\mathrm{Ba}}^{130}$, 359 kev; ${\mathrm{Ba}}^{132}$, 470 kev; ${\mathrm{Ba}}^{135}$, 218 kev; and ${\mathrm{Ba}}^{137}$, 281 kev. Values of reduced transition probability for excitation are given for most of the above gamma rays. In the case of ${\mathrm{Cs}}^{133}$, absolute intensities and branching ratios are given for the gamma rays in the decay of the upper excited states. Level schemes are proposed based on coincidence studies and excitation curves.
