Interacting Boson-Fermion Model description of Ru and Rh isotopes

“…This effect is evident, for instance, in the reduced B(E2) value of the 3/2+~5/2~ transition in mlRu with respect to B(E2; 2 + --,0~ + ) of m2Ru, nicely reproduced both by the exact symmetries [ 13] and the present calculations.…”

“…Odd-mass Rh isotopes are described by a U~ (6) | U~ (6/10) symmetry for low-lying positiveparity states, since the unpaired proton occupies the 1 g9/2 orbital, while negative parity levels are due to protons in 2p~/2, lf5/2 and 2p3/> resulting in an Uv (6 ) | U~ (6/12) symmetry. If the unpaired proton is confined to the 2pl/2 orbital, the latter symmetry reduces to U v (6) | U~ (6/2), and in this case it is possible to derive analytic formulae for energy spectra, which have recently been applied to the analysis of odd-mass Rh isotopes [11,13].…”

Their expressions are given in [14,38] and will not be repeated here.…”

Low-energy Coulomb excitation of 62Fe and 62Mn following in-beam decay of 62Mn

“…The gosia2 version of the code allows for a simultaneous least-squares fit of matrix elements in the target and projectile systems, as well as a common set of normalisation constants, to the observed γ-ray intensities [45]. The target system is over-determined by a complete set of spectroscopic data [48][49][50][51][52][53] plus the observed 3/2 − 1 → 1/2 − 1 intensity, which therefore provides the constraint on the normalisation constant. However, the projectile system is under-determined.…”

gfactors of the low-lying states inPd106: Examination of the vibrational character ofGürdal1, Kumbartzki2, Benczer‐Koller3 et al. 2010Phys. Rev. C

“…In the present investigation, however, lifetimes of the 2 + 2 and 4 + 1 were obtained directly by the Doppler shift attenuation method (DSAM) from the line shapes of the γ transitions. The lifetime of the 2 + 1 state was measured by a plunger experiment [12] and recently remeasured at Yale [13]. In the present work, the g(2 + 2 ) was remeasured while the g(4 + 1 ) was measured for the first time.…”
