Nuclear Shapes in Mean Field Theory

“…several Ta, Re, Ir, Pt, Au, and Hg isotopes (for a cranked NS analysis, see 166,[219][220][221][222]. These proton excitations are analogous to the well deformed intruder states in the Ce region discussed above.…”

“…Other examples of centrifugal stretching can be found in the Os region. CNS calculations utilizing the WS potential predict a considerable stretch ing in the ground-state band of 1 7 6 ,1780S (165,166). For instance, the 4 .…”

“…neutrons penetrate the upper half of the i 13/2 subshell (N � 106) and then polarize the core toward triaxial or nearly oblate originate either from the h ll/2 subshell (again, driving the shape toward strongly negative y values) or they can be built upon the lowest h 9 / 2 and i 1 3/ 2 intruder states, which have a strong tendency to drive the system toward y > 0° because of their particle character (see also Section 7.1). Various scenarios of quasi-particle shape polarization in the W -Hg region are discussed elsewhere (165,166,207,208).…”
