Quadrupole moments of 81+ states in 92,94Mo

Abstract The ratio of the quadrupole moments of the 8 1 + states in 92,94 Mo has been measured as Q( 94 ) Mo Q( 92 Mo ) = 1.48 ± 0.12 by means of the TD PAD method following the 90,92 Zr (α, 2 n ) 92,94 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.
