Collectivity and Configuration Mixing inPb186,188andPo194

Collectivity and configuration mixing in 186,188Pb and 194Po.

Lifetimes of prolate intruder states in 186Pb and oblate intruder states in 194Po have been determined by employing, for the first time, the recoil-decay tagging technique in recoil distance Doppler-shift lifetime measurements. In addition, lifetime measurements of prolate states in 188Pb up to the 8+ state were carried out using the recoil-gating method. The B(E2) values have been deduced from...

Neutron Widths and Configuration Mixing in 11Be

We use known widths and branching ratios in 11Be to discuss Jπ and configuration admixtures. Analysis favors 3/2− for the 3.96-MeV state and three-state mixing for this Jπ .

Collectivity, Chaos, and Computers

Two important pieces of nuclear structure are many-body collective deformations and single-particle spin-orbit splitting. The former can be well-described microscopically by simple SU(3) irreps, but the latter mixes SU(3) irreps, which presents a challenge for large-scale, ab initio calculations on fast modern computers. Nonetheless, SU(3)-like phenomenology remains even in the face of strong m...
