The critical temperature of a gas-liquid type first order phase transition whichis expected to occur in bismuth at low temperature (7':0.1 K) in a strong magneticfield (#:l00k0e) is calculated. Coulomb interaction between the carriers istreated by a mean field theory and the impurity scattering is treated by a self-consistent Born approximation. It is shown that the impurity scattering lowers thecritical temperature, An expression for the critical value of the impurity scattering,which makes the critical temperature vanish, is obtained.
