摘要 In order to investigate the process in which photons are converted into electronpositron pairs in external fields, that is, to calculate the photon attenuation coefficient due to pair creation, usually one should find out the exact electron wavefunction through solving the Dirac equation in external fields, and then calculate the scattering matrices and attenuation coefficient. However, it is often quite complicated to solve the Dirac
