Intermediate-energy Coulomb excitation of ${}^{19}\mathrm{Ne}$

Transition rates from the ground to selected states in ${}^{19}\mathrm{Ne}$ have been measured by their gamma yield following intermediate-energy radioactive ion beam Coulomb excitation. These are compared to corresponding transitions in ${}^{19}\mathrm{F}$ 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 ${\Gamma }_{\gamma }$ 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.
