Abstract

The parent analog of the giant dipole resonance in 28Si is studied by means of the (n, p) reaction. The continuum contribution to the giant dipole region was estimated by a phenomenological parameterization. The observed cross section exhausts 31% of the SJ sum rule; 88% of the GT sum rule or 67% of the Myers-Swiatecki prediction. A comparison is made to the giant resonance region observed in the 28Si(p, p') reaction which was recently used, via comparison to 28Si(α, α'), to infer that the GDR in 28Si is not excited or at least not seen in (p, p').
