Data type PotFrm
This data type is used to describe the potential formulas.
Components of the data type

SymL
 integer, IR component of the continuum orbital on the left sidel of the potential.

SymR
 integer, IR component of the continuum orbital on the right sidel of the potential.

Type
 integer, type of potential formula term,
= 1
for J
type term, = 2
for K type term.

OrbG
 integer, orbital group of the bound orbital.

OrbCL
 integer, IR component of the bound orbital on the left side of the potential term.

OrbCR
 integer, IR component of the bound orbital on the right side of the potential term.

Coef
 real, coefficient for this operator.
