“…In addition to the B(E2) values discussed above, B(M 1) values in 106 Pd have been discussed using IBM2 calculations by Kim et al [27] and by Giannatiempo et al [30]. Indeed, the issue of M 1 strengths was a major component of the paper by Kim et al, and it was the focus of the paper by Giannatiempo et al We note that the two sets of calculations used very different parameter sets, but obtained very similar results for the strongest M 1 (as well as E2) transitions.…”

Excited states in 106 Pd were studied using the (n,n ′ γ) reaction, and comprehensive information for excitations with spin ≤ 6 was obtained. The data include level lifetimes in the femtosecond regime, spins and parities, transition multipolarities, and multipole mixing ratios, which allow the determination of reduced transition probabilities. The E2 decay strength to the low-lying states is mapped up to ≈2.4 MeV in excitation energy. The structures associated with quadrupole collectivity are elucidated and organized into bands.

“…In some cases E2͞M1 mixing ratios were used to tentatively assign MS character to nuclear states with J . 2, e.g., [15,16]. However, the M1 strengths were not measured, rendering the MS assignments uncertain.…”

We identify a Jpi = 3(+)(ms) state in 94Mo. This identification is based on six M1 and E2 strengths and is the first identification of a 3(+)(ms) state from B(M1) and B(E2) values. The transition strengths were determined from the measurement of Doppler shifts, branching ratios, and E2/M1 mixing ratios, obtained from gammagamma directional correlations following the 91Zr(alpha,n) reaction and the beta(+) decay of (94)Tc(m). The interacting boson model agrees with the observations, which prove the 2(+) mixed-symmetry states to be a building block in nuclear structure.

“…Giannatiempo et al [15] have performed interacting boson approximation-2 model calculations of the positive-parity levels in many even-A Pd isotopes, including 106 Pd. While these detailed calculations in the U(5) limit of the model reproduce many of the features of the low-lying structure of 106 Pd, they fail to explain the E2 strengths of decays from the non-yrast states considered here.…”
