Scientific paper

Angle-averaged partial frequency redistribution RII has been employed in obtaining a simultaneous solution of radiative transfer equation in the comoving frame and the statistical equilibrium equation for a non-LTE two level atom. The authors have obtained the ratios of population densities of the upper and lower levels of the resonance line of PV by utilizing the data given in Bernacca and Bianchi (1979). They have considered the atmosphere to be 11 times as thick as the stellar radius. They have also studied the scattering integral.
