B(E2) Values for Low-Lying States in ^144,146Nd Using Coulomb Excitation on a Thick Target
Abstract
B(E2) values have been determined for excited states of ^144,146Nd using Coulomb excitation on a thick target. The experiment was conducted at the Lawrence Berkeley National Laboratory, using the 8π detector array, consisting of 20 Compton-suppressed Ge detectors. 500 MeV ^144,146Nd beams were directed onto thick ^natNi and ^natPb targets. Gamma yields for several states, relative to the 2^+ arrow 0^+(g.s.) transition (with a known B(E2)), were used to obtain the B(E2) values for these states, and relative yields in gated spectra were used to resolve the overlapping 3^- arrow 2^+ and 6^+ arrow 4^+ transitions. E1 and E2 Matrix elements were obtained by comparing yields with results from a Winther-De Boer code analysis. Results will be presented.
