Differential cross sections forγ-transitions to 12 states in28Si following nonresonant proton capture in27Al nuclei (Ep=1,625 keV) were measured and analysed in terms of the direct-semidirect model. The experimental data are reproduced only when the complex coupling constant with the GDR is enhanced for thef partial wave in the entrance channel.
