Title: Intermediate-energy Coulomb excitation of {sup 19}Ne

Abstract

Transition rates from the ground to selected states in {sup 19}Ne have been measured by their gamma yield following intermediate-energy radioactive ion beam Coulomb excitation. These are compared to corresponding transitions in {sup 19}F and to shell model calculations. An upper limit on the cross section of the 4.033 MeV state places a limit on the transition rate and hence on total electromagnetic decay width {gamma}{sub {gamma}} of this state, which is of astrophysical interest. Combining the results with an upper limit on the lifetime of this state and shell model calculations gives an estimate of its width. (c) 2000 The American Physical Society.
