Values depend on which GB model you are using. See pp. 60-61 (and also p. 90)
in the Users' Manual. Recommended values are *not* the vdW radii, but are
mostly modifications of Bondi radii.

Also note the following correction to the manual (from the amber web site):

p. 60
The references to gblambda under PBradii are incorrect. We recommend using
bondi when igb=2, and mbondi when igb=1.
