Multiple dipole bands at prolate shapes in 136Nd and their description through the projected shell model.
Five bands dominated by strong {ital M}1 transitions have been observed in the {sup 136}Nd nucleus. Two of them consist of only dipole transitions, whereas the other three show also weak crossover transitions. The bands have been firmly connected to lower-spin states. Theoretical calculations using the projected shell model suggest quasiparticle configurations involving two protons and two neutrons for the four lowest-lying bands. {copyright} {ital 1996 The American Physical Society.}

ONSET OF COLLECTIVITY IN NEUTRON-DEFICIENT PO-196,PO-198
We have studied via in-beam gamma-ray spectroscopy Po-196 and Po-198, which are the first neutron-deficient Po isotopes to exhibit a collective low-lying structure. The ratios of yrast state energi ...

Shears bands in Pb-193
Four bands of enhanced dipole transitions, with weak crossovers, have been observed in Pb-195. Three of these bands are connected to the spherical levels. in addition, the spherical level scheme ha ...

Lifetimes of the decay from superdeformed to normal deformed in 135Nd.
Lifetimes of low-spin members of the superdeformed band in [sup 135]Nd have been determined by the Doppler-shift recoil-distance method. We find a quadrupole moment of 7.2[sub [minus]1.5][sup +1.2] b for the 677 keV (37/2- 33) / 2 transition in the band, confirming the large deformation previously measured by the Doppler-shift attenuation method. However, the quadrupole moment for the 620 keV transition deexciting the 3.324 MeV (25/2) state at the bottom of the band is much smaller. We conclude that the superdeformed potential-energy minimum disappears or the band drastically changes character at this point which causes the sudden depopulation.

Soft covariant gauges on the lattice.
We present an exploratory study of a one-parameter family of covariant, nonperturbative lattice gauge-fixing conditions that can be implemented through a simple Monte Carlo algorithm. We demonstrate that at the numerical level the procedure is feasible, and as a first application we examine the gauge dependence of the gluon propagator. {copyright} {ital 1996 The American Physical Society.}
