Chemical Potential Jump During Evaporation of a Bose Gas with Variable Molecular Collision Frequency

Evaporation of a binary mixture is considered for the case when the evaporating component is a Bose gas. An analytical solution of the problem of the chemical potential jump of a Bose gas is obtained for the case when the molecular collision frequency of the evaporating component is a variable quantity. The dependence of the coefficient of the chemical potential jump on the evaporation coefficient is investigated. The concentration of the evaporating component is assumed to be much less than that of the carrier gas. A graphical study of the coefficient of the chemical potential jump is presented.
