Solution of the transfer equation in a moving medium

The integral transfer equation for resonance radiation in a semi-infinite medium expanding with a constant velocity gradient is considered. A method for the numerical-analytical solution of this problem is presented, together with an estimation of the associated errors. This method is based on a dis...

Zusammenfassung:	The integral transfer equation for resonance radiation in a semi-infinite medium expanding with a constant velocity gradient is considered. A method for the numerical-analytical solution of this problem is presented, together with an estimation of the associated errors. This method is based on a discretization in optical depth and the application of non-linear equation factorization equations.
