Subject: About the 'mixing' rule of nonbonded parameters

Hi, friend:
  I'm programming based on AMBER 3.0 because of its comparatively simple
structure. Can anyone tell me what is the mixing rule of nonbonded
parameters in Amber 3.0? ( I've heard that for van der Waals radius,
Amber3.0 had used a geometric average: Rij = (Rii*Rjj)**0.5. If it's
true, why? )

  Best regards,
