Background Calculations for (p,n)-Reactions at Intermediate Energies

  • Franz Osterfeld


The background of 40Ca(p,n)- and 48Ca(p,n)-spectra have been calculated in a microscopic model for an incident proton energy of 160 MeV. The continuous parts of the spectra are reproduced within a factor of 1.3. It is shown that most of the background subtracted in the experimental analysis of the 48Ca(p,n)-Gamow-Teller resonance is actually Gamow-Teller strength. The calculations predict a strong ΔL=2(3+)-resonance in 48Ca(p,n) at 25 MeV excitation energy, but none in 40Ca.
