Electric-Quadrupole Moment of the First Excited State of exp 12 C

摘要

The static electric-quadrupole moment Qsub(2+) of the first excited state of exp 12 C has been measured using Coulomb excitation of exp 12 C projectiles by a exp 208 Pb target. The result is Qsub(2+) = 6+-3 e.fm exp 2 , which indicates a substantial oblate deformation, consistent with most theoretical expectations. (Atomindex citation 14:753578)
