Dear Netters,
Could anyone tell me what the form for the Slater
Exchange Functional used by Gaussian 92? Exactly what are
the differences between the Slater Functional and the Xalpha
functional?
Both use Rho^(4/3). Hartree-Fock-Slater uses the theoretical value of
2/3 for the coefficient in front while Xalpha requests the commonly
used empirical value of 0.7
