Abstract

With the use of a fragment mass analyzer, the $α$ decay of $^{180} Tl$ was identified in $^{92} Mo$ bombardments of $^{90} Zr .$ At least three α transitions were observed but on the basis of the data obtained it was not possible to conclude if they originate from one or more levels in $^{180} Tl .$ In the same irradiations a new α group was also identified in $^{179} {Tl}^{m}$ decay. Based on energy and half-life systematics, it appears that $^{179} {Tl}^{m},$ in contrast to the isomers in heavier odd-A Tl nuclei, is not the $h_{9 / 2}$ intruder level but rather the $h_{11 / 2}$ proton state.
