Inelastic proton scattering (I). Ar40 and Ca40

Effective interactions and the40Ca(p, p′) reaction

“…These fits to the data are comparable to those obtained with a Yukawa interaction which fits low-energy nucleon-nucleon scattering [5] or with the Kallio-Koltveit interaction [4], although both give cross sections which are larger by about a factor of 2 than does the HL Fig. 5 shows the results using the renormalized densities at 17, 20, and 25 MeV, compared to the data [20][21][22]. The fits here are comparable, but appear to deteriorate as the energy is lowered.…”

Nuclear gamma-rays from energetic particle interactions

“…The strongest deexcitation line from 40Ca is at 3.736 MeV from the first gamma decay level. The cross section for proton excita tion of this level has been measured at 14.6 and 17.3 MeV by Gray, Kenefick and Kraushaar (1965), at 30 MeV by Ridley and Turner fsee Satchler, 1973), at 55 MeV by Yagi et al (1964), and at -155 MeV by Willis et al (1968) and Roos and Wall (1965).…”
