The Quadrupole Moments of the First Excited 2⁺States in^{96 100 104}Ru

Abstract

The quadrupole moments of the first excited 2+ states in 96,100,104Ru have been measured using the reorientation precession technique. In 104Ru the sign of the Coulomb interference term P4 = M0+12+1 M0+12+2 M2+22+1 × M2+12+1 was determined and found to be P4 < 0. The quadrupole moment in 104Ru was determined to be -0.76 ± 0.19 eb. In 96Ru and 100Ru the measurements revealed quadrupole moments of -0.15 ± 0.27 eb and -0.40 ± 0.12 eb, respectively, independent of the sign of P4. The experimentally determined values are compared with theoretical calculations.
