| Abstract: | The inelastic scattering of 46.8MeV antiproton by 12C leading to the excitation of one normal parity T=0 levels is studied in the framework of Glauber model. The transition densities obtained from fitting to the electron scattering data and the three annihilation potentials derived from analysis of p—p scattering data are used in the calculation. The inelastic angular distribution for exciting the lowest normal parity T=0 states in 12C at 4.44MeV (Ｊπ＝２＋) by 46.8MeV antiproton are calculated by selecting potential parameter suitably. The results are seen to be in fairly good agreement with the available experimental data. The results are given by comparing the elementary two-body amplitudes. |
| Keywords: | Glauber theory antiproton inelastic scattering annihilation potential the transition densities |
