Abstract

Use was made of a special feature in the detection of unbound ejectiles, to extend previous measurements of the ( $α$ , $α^{*}$ ) reaction on ${}^{24}{Mg}$ and ${}^{28}{Si}$ to very forward angles. The characteristic differential cross sections obtained for mutual as well as for single excitation are well reproduced in a full coupled-channels calculation in which the strong couplings to the first excited $2^{+}$ states of the target nuclei are taken into account.
