Possible antimagnetic rotational band and neutron alignment in101Pd

Band structures in Pd101

“…The γ ray transition energies in general agree within ∼ 1 keV with those given by Sugawara et al [22] [8,9,35], and 102 Ag [28]. The present values deduced from high statistics data using double gated spectra are more reliable.…”

“…It increases up to 1.0 keV for the weak high energy γ rays. The previously observed positive-parity band B1 based on the 5/2 + ground state [21,22,33,34] has been extended up to I π = (41/2) + with addition of the 1297-and 1494 keV transitions (Fig. 2).…”

“…2) consists of positive-parity bands B1, B2, B6, and B7, and negative-parity bands B3, B4, and B5. The earlier reported level schemes [21,22,33,34] are modified and extended significantly at medium spins with addition of more than 100 new γ transitions. Because of larger fraction of the higher-fold γ ray coincidence events collected using INGA and enhanced efficiency using clover detectors in the add-back mode, a large number of weak γ transitions could be placed in the level scheme.…”

“…2). The structure of band B2 above the 4528 keV 27/2 + state [22] is extended further to evolve into a coupled structure consisting of the 665-525-597-912 keV dipole cascade along with the 1190-and 1509 keV crossover transitions [ Fig. 3 (a)].…”

“…Prior to this work, high spin states in this nucleus have previously been investigated by Zhou et al [21] and Sugawara et al [22] via the 76 Ge( 28 Si, 3n) and 68 Zn( 37 Cl, p3n) reactions, respectively, and using small arrays of Ge detectors with BGO anti-Compton shields. The quasirotational bands built on the νd 5/2 , νg 7/2 , and νh 11/2 orbitals, and the related configurations have been reported in 101 Pd.…”
