               BECKE_ROUSSEL| &BECKE_ROUSSEL {Logical} | |
| activates the functional | |
| This keyword cannot be repeated and it expects precisely one logical. | |
| The lone keyword behaves as a switch to .TRUE. | |
| Default value: .FALSE. | 
| CUTOFF_RADIUS {Real} | |
| Defines the cutoff radius for the truncation. If put to zero, the standard full range potential will be used | |
| This keyword cannot be repeated and it expects precisely one real. | |
| Default value: 0.00000000E+000 | 
| GAMMA {Real} | |
| Parameter in the exchange hole. Usually this is put to 1.0 or 0.8 | |
| This keyword cannot be repeated and it expects precisely one real. | |
| Default value: 1.00000000E+000 | 
| SCALE_X {Real} | |
