Dispersion coefficients for H and He interactions with alkali-metal and alkaline-earth-metal atoms

Research output: Contribution to journal › Article

Abstract

Nonrelativistic model potential analysis for the alkali-metal atoms was performed giving dispersion coefficients and polarizabilities that are in excellent agreement with relativistic MBPT calculations. Taking the results in conjunction with the MBPT data leads to the conclusion that the leading dispersion parameter C 6 for the alkali-metal hydrides is known with a precision of about 1%.
