  • The inelastic scattering of antiproton (plab=600MeV/c) by 12C leading to the excitation of the three 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 pp scattering data are used in the calculation. The inelastic angular distribution for exciting the three lowest normal parity T=0 states in 12C at 4.44MeV(Jπ=2+), 7.66MeV(Jπ=0+), and 9.63MeV(Jπ=3-) by 600MeV/c 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 using the elementary two-body amplitudes comparatively.

Abstract: The inelastic scattering of antiproton (plab=600MeV/c) by 12C leading to the excitation of the three 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 pp scattering data are used in the calculation. The inelastic angular distribution for exciting the three lowest normal parity T=0 states in 12C at 4.44MeV(Jπ=2+), 7.66MeV(Jπ=0+), and 9.63MeV(Jπ=3-) by 600MeV/c 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 using the elementary two-body amplitudes comparatively.
