Abstract

The quadrupole moments and deformations have been measured for six superdeformed bands in ¹⁵⁰Gd. The results indicate evidence for deformation driving properties of both the high-N intruder and also low-N natural parity states at the superdeformed Fermi surface. Several new transitions have been identified and placed in the low spin non-yrast portion of one of the SD bands.

Nuclear Data Sheets for A=150
2013, Nuclear Data Sheets
The experimental results from the various reaction and decay studies leading to nuclides in the $A = 150$ mass chain have been reviewed. These data are summarized and presented, together with the adopted level schemes and properties, for the nuclides from Cs(Z=55) through Lu(Z=71). This evaluation replaces the previous evaluation by E. der Mateosian and J. K. Tuli (1995De28), which appeared in Nuclear Data Sheets 75, 827 (1995).
Approximate particle number projection with density dependent forces: Superdeformed bands in the A = 150 and A = 190 regions

They display the typical Coriolis effects: first an increase caused by the Coriolis antipairing effect and later one the Coriolis antistretching effect. It is in good agreement with the experimental value, 17±0.50.4 eb [38]. This nucleus is also axially symmetric.
We derive the equations for approximate particle number projection based on mean field wave functions with finite range density dependent forces. As an application ground bands of even-A superdeformed nuclei in the A=150 and A=190 regions are calculated with the Gogny force. We discuss nuclear properties such as quadrupole moments, moments of inertia and quasiparticle spectra, among others, as a function of the angular momentum. We obtain a good overall description.
Comparative quadrupole moments of superdeformed bands in <sup>193-196</sup>Pb
1998, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
Lifetimes have been measured for states in five superdeformed yrast bands in ^193−196Pb using the Gammasphere spectrometer array. Centroid shifts and lineshapes of transitions showing attenuated Doppler shifts have been analyzed. Transition quadrupole moments are deduced for the five bands including, for the first time, bands of two odd-A Pb isotopes. The quadrupole moments are found to be remarkably similar for the yrast bands in ¹⁹⁴Pb (band 1), ¹⁹⁵Pb (bands 1 and 2) and ¹⁹⁶Pb (band 1) (Q_t≈20 b). However, for ¹⁹³Pb a smaller value, Q_t=17.3(7) b, is obtained. This can be explained in terms of the occupation of the neutron N = 7 intruder orbitals.
