Effect of Debye plasmas on the dispersion coefficients C{sub 8}, C{sub 10}, and C{sub 12} for interactions between atoms has been investigated using highly accurate correlated exponential basis functions. In the free-atom case, the dispersion C{sub 12} coefficient and the hexadecapole polarizability for helium are reported. The dispersion coefficients, hexadecapole polarizability, and 1s5g {sup 1}G{sup e} state energy of helium for different screening parameters are also reported.
