Study of mixed-symmetry states in $^{94}_{40}$Zr with (n,n$'\gamma$) reaction

The low-spin structure of $^{94}_{40}$Zr has been studied with the $(n,n'\gamma)$ reaction at the University of Kentucky 7 MV Van de Graaff acelerator facility and at TUNL at Duke University. Branching ratios, lifetimes, multipolarities and spin assignments have been determined. The 2$^{+}_{2}$ state at 1671.4 keV has been identified as the lowest mixed-symmetry state in $^{94}$Zr; $B(M1; 2^{+}_{1,ms} \rightarrow 2^{+}_{1})$ = 0.33(5) $\mu^{2}_{N}$. This state has an anomalous decay behavior, i.e., $B(E2; 2^{+}_{1,ms} \rightarrow 0^{+}_{1})$ = 8(1) W.u. is unusually larger compared to the $B(E2; 2^{+}_{1} \rightarrow 0^{+}_{1})$ = 4.9(11)W.u. The analysis of angular distribution data reveals even more anomalies in the states above the mixed-symmetry, 2$^{+}_{1,ms}$, state. For example, the 4$^{+}_{2}$ state, at 2330 keV decays strongly to the 2$^{+}_{1}$ state, $B(E2; 4^{+}_{2} \rightarrow 2^{+}_{1})$ = 19(2) W.u. compared to the 4$^{+}_{1}$ state at 1470 keV, $B(E2; 4^{+}_{1} \rightarrow 2^{+}_{1})$ = 0.88(2) W.u. Some results from the angular distributions data at $E_{n}$=2.8 and 3.5 MeV will be presented to address this issue.
