The first excited $0^{+}$ state of ${}_{}{}^{82}{}_{}{}^{}\mathrm{Kr}$ appears to have a noncollective nature, in contrast to the $0_3^{+}$ and other low-spin states in this nucleus. This is corroborated by a conversion-electron measurement of the $0_2^{+}$→$0_1^{+}$ and the $0_3^{+}$→$0_1^{+}$ transitions in ${}_{}{}^{82}{}_{}{}^{}\mathrm{Kr}$, following the decay of ${}_{}{}^{82}{}_{}{}^{}\mathrm{Rb}_{}^{\mathrm{g}}{}_{}{}^{}$. The values B(E${0;0}_2^{+}$→$0_1^{+}$)=3.1 (5) $e^2$${\mathrm{fm}}^4$ and $X_{311}$=B(E${0;0}_3^{+}$→$0_1^{+}$ $2_1^{+}$)=0 .097(24) have been deduced from the intensities of the conversion lines, observed with a mini-orange spectrometer.
