Abstract
Electromagnetic transitions from low-lying 0+, 2+, 4+ and 3− states in102, 104Pd have been studied using (p, 2n) and (p, p′) reactions and Coulomb excitation. TheE2 transition probabilities from the 0 +3 state in102Pd (13 W.u.) and from the 02/+ state in104Pd (14 W.u.) are somewhat low for two-phonon states. Generally, theE2 transition rates are reasonably well reproduced by the IBA-2 and by the boson-expansion description. The intruding 0 +2 state (t1/2=14.3 ns) in102Pd is connected to the 22/+ and 2 +3 states via strong E2 transitions: B(E2; 0 +2 → 2 +2 )=96±40 W.u.; B(E2; 2 +3 → 0 +2 =17±11 W.u.
