“…3(b), which indicates that the TSD bands have larger deformation than the ND band. The J (2) values are close to those of the TSD bands in 168 Hf where the transition quadrupole moment of band TSD1 has been measured to be Q t ≈ 11.4 e b [17], which is substantially larger than Q t ≈ 6.4 e b for the ND yrast band [18].…”

“…The excited positiveparity neutron is in an N = 6 level (νi 13/2 ) for the N(1, 0) configuration and in an N = 4 level (∼ 30% νg 7/2 occupation) for the N(1, 2) configuration. These are not the same as in 168 Hf where a νj 15/2 neutron level is occupied in the TSD bands [18]. Bands TSD1 and AE can be associated with coexisting energy minima in the lowest P(0, 0)N(1, 2) TES (Fig.…”

Nuclear pairing reduction due to rotation and blocking

et al. 2011

Nuclear pairing gaps of normally deformed and superdeformed nuclei are investigated using the particle-number conserving (PNC) formalism for the cranked shell model, in which the blocking effects are treated exactly. Both rotational frequency ω-dependence and seniority (number of unpaired particles) ν-dependence of the pairing gap∆ are investigated. For the ground-state bands of even-even nuclei, PNC calculations show that in general∆ decreases with increasing ω, but the ω-dependence is much weaker than that calculated by the number-projected Hartree-FockBogolyubov approach. For the multiquasiparticle bands (seniority ν > 2), the pairing gaps keep almost ω-independent. As a function of the seniority ν, the bandhead pairing gaps∆(ν, ω = 0) decrease slowly with increasing ν. Even for the highest seniority ν bands identified so far,∆(ν, ω = 0) remains greater than 70% of∆(ν = 0, ω = 0).

High-spin states in 138 Nd were investigated by using the 48 Ca + 94 Zr reaction and γ -ray coincidences were acquired with the GASP spectrometer. A rich level scheme was developed including 14 new bands of quadrupole transitions at very high spins. Linking transitions connecting 11 high-spin bands to low-energy states have been observed. Calculations based on the cranked Nilsson-Strutinsky formalism have been used to assign configurations to the observed bands. The main result of these calculations is that all 14 bands exhibit a stable triaxial deformation up to the highest observed spins, giving strong support to the existence of a triaxial minimum with normal deformation and positive asymmetry parameter in nuclei with a few holes in the N = 82 shell closure.
