Abstract
Radiative -particle capture into the first excited, state of at 6.049 MeV excitation energy has rarely been discussed as contributing to the reaction cross section due to experimental difficulties in observing this transition. We report here measurements of this radiative capture in for center-of-mass energies of to 5.42 MeV at the DRAGON recoil separator. To determine cross sections, the acceptance of the recoil separator has been simulated in GEANT as well as measured directly. The transition strength between resonances has been identified in -matrix fits as resulting both from contributions as well as radiative capture. Details of the extrapolation of the total cross section to low energies are then discussed [] showing that this transition is likely the most important cascade contribution for .
