摘要
在Glauber多重散射理论框架下 ,使用跃迁密度方法和 3种 NN湮没势 ,计算了入射动量为6 0 0MeV c的反质子在12 C上的非弹性散射微分截面 .
The inelastic scattering of antiproton (p lab=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 p 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(J π=2 +), 7.66MeV(J π=0 +), and 9.63MeV(J π=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.
