Abstract
Two techniques for determining B(E2:0(1)(+)--> 2(1)(+)) values using
low-energy Coulomb excitation of Radioactive Nuclear Beams in inverse
kinematics are presented. One method, applicable if the lifetime of the
excited state is similar to 1 ns, uses a linear array of NaI(T1)
detectors to measure the decay curve, and thus the 2(1)(+) state
lifetime, for Coulomb excited radioactive beam nuclei as they decay in
flight downstream from a carbon excitation target. In the second method,
useful when lifetimes are short, <1 ns, or for low intensity beams, a
through-well NaI(T1) detector is used to measure the Coulomb excitation
cross section from which the B(E2:0:(+)(1)--> 2(1)(+)) value is
calculated. The results of test experiments with beams of stable Os
isotopes are presented.
