OSTI ID:5910060
The radiative {sup 3}He capture reaction on {sup 12}C was measured over the energy region E{sub 3He} =12-25 MeV. The {gamma}-ray was measured by two 25.4 cm long and 25.4 cm in diameter NaI(Tl) spectrometers surrounded by anticoincidence plastic shields. Excitation functions at {theta}{sub lab} =60{degrees} and 105{degrees} have been measured for captures populating the ground and various excited states of {sup 15}O. Angular distribution have been measured at E{sub 3{sub He}} = 18.9 MeV. The existence of giant resonances built on the excited states of {sup 15}O was investigated. Calculations from a phenomenological direct-semidirect cluster model were performed to bound and unbound final states in {sup 15}O to determine the magnitude and the energy dependence of the cross section as well as the angular distributions. The calculations showed a reasonable agreement with the excitation function.
