低能正电子与氖、氩原子弹性碰撞截面的理论计算

CALCULATION FOR TOTAL CROSS SECTIONS AND MOMENTUM TRANSFER CROSS SECTIONS OF THE ELASTIC SCATTERING OF LOW-ENERGY POSITRON BY Ne AND Ar

本文把Khara与Moiseiwitsch极化势推广应用到多电子靶原子散射,并利用等效势模型计算了低能正电子与氖、氩原子弹性碰撞截面,我们的计算结果与别人理论计算及实验都符合的比较好。

Khara and Moiseiwitsch's polarization potential have been popularized to many electrons target atom scattering, and by using of the effective potential model, we have been calculated the total cross sections and momentum transfer cross sections of elastic scattering of low-energy positron by neon and argon. Our reults are in good agreement with other theoretical results and experiment datum.
