Quadrupole moment of the first excited state of 32S

The static quadrupole moment and B(E2; 0+ → 2+) value for the first excited state of 32S were measured using the reorientation effect in Coulomb excitation of 32S projectiles. Silicon surface barrier detectors were used to detect 32S ions scattered from 208Pb at mean laboratory angles of 900 and 1740, for bombarding energies in the range 122 to 160 MeV. The results for constructive (destructive) interference from the second 2+ state in 32S are Q2sub(+) = - 16.0 +- 2.2 (- 13.3 +- 2.2) e x fm2 and B(E2; 0+ → 2+) = 292 +- 17 (307 +- 17) e2 x fm4.
