Discovery and assignment of excited0+levels in even-AMo isotopes

The first excited $0^{+}$ levels, some of which are previously unobserved, in each of the even-$A$ isotopes 92, 94, 96, and 100, have energies of 2517 ± 0.5, 1742 ± 2, 1147, and 694 keV, respectively. These states were identified using $\gamma$-ray data from ($n,n^{\prime }\gamma$) reactions and the strong anisotropy of the angular distribution of ($n,n^{\prime }$) reactions in $0^{+}$ → $0^{+}$ transitions.
