Re: CCL:slater exchange functional for g92



 Scott Boesch asked
     	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
