Classical Path Broadening Functions for a Debye-Shielded Interaction,
Abstract
Stark broadening calculations of isolated neutral atom lines in the classical path approximation usually involve an electron (moving along a straight line path) interacting directly with the atom. Correlations between the electrons are then taken into account by imp sing a cutoff in the interaction, when the distance from the atom, rho exceeds the Debye length, rho sub D. A more consistent procedure for the correlation effects is to replace the direct interaction of the electron by a Debye-shielded interaction. The functions A, B, a and b which are required in the theory when the Debye-shielded interaction is used are considered in detail in this report. When rho/rho sub D < 0.1, it is found that the a and b functions may be closely reproduced by using unshielded functions in conjunction with an upper cutoff of 0.68 rho sub D. (Author)
