库仑势的经典散射和量子散射

Classical and quantum scattering by a Coulomb potential

A. I. Nikishov

摘要:

对于相对论能量,库仑势上散射的小角经典截面仅在首项上与标量粒子的量子截面的第一玻恩近似一致。如果对足够大的库仑电荷的第一玻恩近似的所有修正之和包含与该电荷无关的经典项,则可以避免在其他项上的不一致。经典和量子截面的差异有一小部分可能归因于相对论性量子粒子可以在没有相互作用的情况下冲过场。我们预计较小的碰撞参量和自旋会促进这种影响。

英文摘要:

For relativistic energies the small angle classical cross section for scattering on a Coulomb potential agrees with the first Born approximation for quantum cross section for scalar particle only in the leading term. The disagreement in other terms can be avoided if the sum of all corrections to the first Born approximation for large enough Coulomb charge contain the classical terms which are independent of that charge. A small part of the difference in classical and quantum cross sections may be attributed to the fact that the relativistic quantum particle can rush through the field without interaction. We expect that smaller impact parameters and spin facilitate this affect.
