摘要:

我们已经进行了计算的包容性电子散射截面关闭对应于700和1200 MeV之间的电子束能量,准弹性散射和单π生产的主要反应机制的运动学区域。发展和成功地应用于描述准弹性散射的形式主义已经扩展到包括δ生产和非共振π介子生产。在整个能量传递范围内,包括准弹性峰和第一共振之间的倾斜区域,结果与实验数据相当吻合。

英文摘要:

We have carried out a calculation of the inclusive electron scattering cross section off oxygen in the kinematical region corresponding to beam energies between 700 and 1200 MeV, where quasielastic scattering and single pion production are the dominant reaction mechanisms. The formalism developed and successfully applied to describe quasielastic scattering has been extended to include both delta production and non-resonant pion production. The results are in fairly good agreement with experimental data over the whole range of energy transfer, including the dip region between the quasielastic peak and the first resonance.
