摘要:

微分截面的过程gn-->pi-p已提取的MAMI-B测量gd--> pi-pp,占终态相互作用的影响,使用一个图形技术,考虑到NN和piN的终态相互作用振幅。结果进行了比较,以前的测量的逆过程,π-p--> ng,和最近的多极分析。

英文摘要:

Differential cross sections for the process gn-->pi-p have been extracted from MAMI-B measurements of gd-->pi-pp, accounting for final-state interaction effects, using a diagrammatic technique taking into account the NN and piN final-state interaction amplitudes. Results are compared to previous measurements of the inverse process, pi-p--> ng, and recent multipole analyses.
