3. DESCRIPTION OF PROGRAM OR FUNCTION
Several types of calculations and combinations can be performed including a standard Weisskopf- Ewing evaporation with multiple particle emission, S-wave approximation to give an upper limit to the enhancement of gamma-ray deexcitation due to momentum effects, and an evaporation calculation that can include fission competition via the Bohr-Wheeler approach. ALICE91 calculates precompound decay via Hybrid and GDH models with multiple precompound decay algorithms, single and double differential spectra, and reaction product cross sections.

4. METHOD OF SOLUTION
ALICE/85/300 and later revisions of the ALICE/LIVERMORE 82 computer code do precompound, compound/ statistical fission calculations in the general framework of the Weisskopf-Ewing evaporation model, the Bohr-Wheeler transition state model for fission, and the hybrid/geometry dependent models for precompound decay. ALICE/85/300 allows a variable energy mesh size, excitation energies up to 300 MeV, and incorporates several other improvements in calculational approaches.
ALICE91 includes options for shell dependent level densities, and an option to use systematics for angular distribution. The new version also includes gamma-ray competition with particle decay models.
The IBM PC version (B) was converted from mainframe ALICE-87, which is a revision of ALICE/85/300. Input default options were included in this version. Refer to comments in the file ALICE1.FOR for information on modifications. ALISO differs only in that it will do calculations for natural isotopic targets, giving weighted results at the end.

6. TYPICAL RUNNING TIME
The sample input took about 6 seconds of CPU time on the Cray XMP under UNICOS. The sample case for ALICE-87 took 23 minutes on an IBM PC/XT running at 4.7 megahertz with a math co- processor. The ALISO case took 4 minutes on the same computer.
