Description

The effect of particle emission on the peak shape of γ-ray lines have been investigated using the NORDBALL detector system. By detecting neutrons, protons and α particles emitted in the 32S (95 MeV) + 27Al reaction, the energy and direction of emission of the residual nuclei could be determined and subsequently used for an event-by -event Doppler correction of the detected γ rays. Extensive Monte Carlo simulations were performed to study how the different Doppler phenomena influence the peak shape and in particular which particle detector properties are important for the Doppler correction.
