Projectile Coulomb excitation of 24Mg

Abstract

The static quadrupole moment of the first excited Jπ = 2+ state in 24Mg and the reduced electric quadrupole transition probability between this state and the ground state were measured via projectile Coulomb excitation. The quadrupole moment was deduced from the shapes of γ-ray angular distributions. The result is Q(24Mg, 2+) = −0.27±0.05 b. The transition strength was deduced from yield measurements and by comparison with the yields of target γ-rays, The result is B(E2; 0+ → 2+, 24Mg) = 0.044±0.003 e2 · b2. The experimental measurements are compared with theoretical predictions and previous measurements and a detailed discussion is given of corrections to this type of reorientation experiment.
