An attempt has been made to reduce the input data Regional Computing Centre as far as is reasonable, so that users who are not familiar with the programme can run it reliably. Both post and prior for-Operating system: UMRCC Scope V2. 1 malisms are possible and agreement between the two can be obtained to within 1%. Programming language used: FORTRAN Restrictions on the complexity of the problem High speed storage required: 40 K words The program deals only with one step transfer of spin ~or spin zero particles. It does not allow for spin orbit forces in No. of bits in a word: 60 the distorted waves. It is restricted to 124 partial waves, although this limit could easily be increased. Overlay structure: none The maximum bound state orbital angular momentum is 1 = 8.
