Abstract
The giant-resonance region in Ca-40 and Ca-48 has been studied using the re actions Ca-48(p,p' n(0))Ca-47, Ca-40(p,p' p(0))K-39, and Ca-40(p,p' alpha ( 0))Ar-36 for incident proton energy E-p = 100 MeV. Knockout cross sections for these reactions were calculated within the distorted wave impulse appro ximation formalism using parameters fixed from previous investigations. The results quantitatively account for the data at higher excitation energies while the knockout contributions underneath the main resonance strength are small.
