The T > giant resonance of 181Ta

Abstract The energy distributions and the cross sections of the (e, e'p) reaction on 181 Ta have been measured. The derived (γ, p) cross section shows a strong resonance at around 21 MeV which is identified as the T > giant resonance. Two large proton groups were found in the proton spectra measured at E e > 20.0 MeV. These proton groups and another small proton group are found to result from the resonance at around 21 MeV. The proton groups are well described by the calculation of the T > giant resonance with the Nilsson model
