Abstract

The reorientation effect in Coulomb excitation has been used to measure the following static electric quadrupolemoments:Q2+(28Si) = +17.5 ± 2.9 e · fm2, Q2 (32S) = −11.5 ± 4.8e · fm2 and Q2++(34S) = +6.3 ± 4.3 e · fm2. Energy spectra from the 208Pb+28Si, 32, 34S reactions at E = 105–122 MeV were obtained with the Chalk River Q3D spectrometer. These data were fitted with accurate B(E2; 0+ → 2+) values determined from a weighted average of all previous measurements combined with those measured by the Doppler shift attenuation method by using the inverse reactions 4He(32, 34S, α) where the mean 2+1 state lifetimes were found to be 0.236 ± 0.016 ps (32S) and 0.442 ± 0.026 ps(34S).
