Collective and two-quasiparticle excitations inPd102,104,106

High-spin structure of104Pd

“…The DCO ratios obtained in this way for already known transitions of 104 Pd are consistent with the previous assignments of Grau et al [13] and Stromswold et al [14] except for some minor differences. Grau et al assigned I = 1 M1 + E2 multipolarity to the 350 keV transition, while we propose I = 0 dipole character for this γ ray.…”

“…The order of the transitions in the γ -ray cascades was deduced from the intensity relations when no other information was available. The placement of the known transitions is consistent with the previous works [13][14][15] except that our coincidence data did not support the existence of the 941 keV γ ray assigned to 104 Pd by Grau et al [13]. The already known bands (bands 1, 3, 4, and 8) were extended to higher excitation energy and spin.…”

“…The yrast band 1 has been previously reported up to 8h [13][14][15]. In the present work it was extended up to an excitation energy E x = 5.4 MeV with two additional levels decaying by the 1019 and the 1148 keV transitions.…”

“…The 13 C beam, provided by the the Vivitron accelerator at IReS, Strasbourg, impinged on a stack of two targets, each of thickness 558 μg/cm 2 and enriched to 86% in 96 Zr. The emitted γ rays were detected by the Euroball IV detector array [16] equipped with 15 cluster [17] and 26 clover [18] composite Ge detectors.…”

“…In the latter nucleus several two-quasiparticle bands have been established [12], and thus appearance of similar structures is expected in 104 Pd. Collective and two-quasiparticle excitations in 104 Pd have been previously studied via the 94 Zr( 13 C,3nγ ) reaction by Grau et al [13]. High angular momentum, positive-and negativeparity states have been identified in this work using excitation function, γ -ray angular distribution, γ -ray linear polarization, and γ γ -coincidence measurements.…”
