maximum cutoff radius found in Description section
must be supplied
Determines the core radius for the pseudopotential generation.
At the core radius the logarithmic derivatives of the
AE-wavefunctions and the pseudo wavefunctions are matched.
For some schemes (TM and RRKJ) this core radius can be similar
to the cutoff radius
supplied in the Description section of the PSCTR file
13.4.11. For these schemes the pseudo wavefunction
is strictly the same as the AE-wavefunction for . This
is not the case for the BHS, VAN and XNC scheme. Here
RCORE must be supplied by the user and should be 1.5 times
as large as the maximum cutoff radius .
