Application of the Particle-Hole Model to Electro-Excitation and Muon Capture in Light Nuclei

摘要

In the framework of the one-particle, one-hole model with a Serber residual interaction the negative parity J = 0, 1 and 2, T = 1 eigenstates are calculated. These results are then used to determine the E1 and M2 squared reduced matrix elements for inelastic electron scattering for values of momentum transfer from 0 to 300 MeV/c. The nucleon decay widths of the 1(-) and 2(-) states are calculated from R-matrix theory and used in conjunction with the E1 and M2 matrix elements and the Breit-Wigner formula to determine the excitation spectra for photonuclear and 180 deg. inelastic electron scattering reactions. In addition, the matrix elements for muon capture are calculated for all three couplings and the total muon capture rate is determined. Results are presented for each of the five, light, magic number nuclei 12C, 16O, 28Si, 32S, and 40Ca. (Author)
