| Abstract: | Two different relaxation times for electrons in a plasma are calculated using the kinetic equation with collision terms, with the influence of magnetic field included. Under the condition prevailing on the surface of white dwarfs and neutron stars, i. e., with magnetic fields as strong as 10sT and electron density of 1026-1027cm-3, and at a temperature of 10 keV, the results are compared with that obtained neglecting the influence of magnetic field. It is found that this effect increases the relaxation time considerably and can not be neglected in quantitative evaluations. |
