|for TM and RRKJ||maximum cutoff radius found in Description section|
|else||must be supplied|
Determines the core radius for the pseudopotential generation. At the core radius the logarithmic derivatives of the AE wave functions and the pseudo wave functions 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 11.4.11. For these schemes the pseudo wave function is strictly the same as the AE wave function 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 .
