Jakubassa-Amundsen, D. H.; Ponomarev, V. Yu (2020): On the excitation of the 2(1)(+) state in C-12 in the (e, e ' gamma) reaction. In: European Physical Journal A, Vol. 56, No. 6, 162

Abstract

The excitation of the carbon 2(+) state at 4.439 MeV by 70-150 MeV electron impact and its subsequent decay to the ground state by photon emission is described within the distorted-wave Born approximation. The transition densities are obtained from the nuclear quasiparticle phonon model. The photon angular distributions are compared with earlier results and with experiment, including the influence of bremsstrahlung. Predictions for spin asymmetries in the case of polarized electron impact are also made.
