Long-range potential scattering: Converting long-range potential to short-range potential by tortoise coordinate
Wen-Du Li, Wu-Sheng Dai
Inspired by general relativity, we suggest an approach for long-range potential scattering. In scattering theory, there is a general theory for short-range potential scattering, bu…
