3. DESCRIPTION OF PROGRAM OR FUNCTION - CADE calculates reaction cross sections for multi-particle emission. The total cross section for the emission of a particle at any particular stage is calculated together with the cross section as a function of energy. The probability of leaving the final nucleus in a state of any particular energy is also obtained.


4. METHOD OF SOLUTION - The program performs compound nucleus calculations using the Weisskopf-Ewing formalism. Multi-particle emissions are treated as a series of stages in a cascade. The relevant compound nucleus absorption cross sections for particle channels are calculated with built-in optical model routines. The gamma-ray emission is described by the giant dipole resonance formalism.


5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - 


6. TYPICAL RUNNING TIME - 

NEA-1020/01:

NEA-DB compiled the program on IBM 3090 and VAX 8810 computers and executed the test case included in this package. Execution times required were: 2 seconds (IBM); and 12 seconds (VAX)


7. UNUSUAL FEATURES OF THE PROGRAM - Several choices for the final nucleus level density formula may be made using the leval density routine contained in the program.
