Title: Electric quadrupole moment of the /sup 211/Rn (63/2)/sup -/ isomer: Absence of core deformation at very high spins

Journal Article · · Phys. Rev. Lett.; (United States)

The electric quadrupole moments of /sup 211/Rn isomers were determined as Q((17/2)/sup -/) = 19(2) exfm/sup 2/ and Q((63/2)/sup -/) = 160(22) exfm/sup 2/ via measurements of the quadrupole interaction in a Bi single-crystal host. The results indicate that the spherical shape is preserved in the lead region even at the core-excited very high-spin regime, in contradiction to theoretical predictions.
