Quadrupole moments of 81+ states in 92,94Mo

The ratio of the quadrupole moments of the 8₁⁺ states in ${}^{\mathrm{92,94}}\text{Mo}$ has been measured as $\text{Q(}{}^{94}\text{)}\text{Mo}\text{Q(}{}^{92}\text{Mo}\text{)}\text{= 1.48 ± 0.12}$ by means of the TD PAD method following the ${}^{\mathrm{90,92}}\text{Zr}\text{(α, 2}\text{n}\text{)}{}^{\mathrm{92,94}}\text{Mo}$ reactions on enriched Zr metal foils. This ratio is consistent with the effective charge ratio for the 8⁺ → 6⁺E2 transitions which demonstrates a prediction of the effective charge concept.
