摘要：
The effect of Debye-Huckel screening on the dispersion coefficients C-6, C-8, C-10 for interactions among H, Li, Na and K atoms has been investigated using the symplectic algorithm. The C-6, C-8, C-10 coefficients for interactions among alkali-metal atoms along with the dipole, quadrupole and octupole polarizabilities of K atom for various screening parameters are reported for the first time in the literature. In free-atomic cases, our results are comparable with available theoretical and experimental results. (C) 2012 Elsevier Ltd. All rights reserved.
