Dear KSUEFF User: You have been sent seven files to enable you to run the Kent State neutron detector efficiency code. These files are: 1. INSTR.LIS - Brief instructions for using the code. 2. VAXEFF.FOR - The fortran source version which can run on a VAX computer. 3. 20BY40.DAT - A sample input file. 4. CROSEC.IN - the cross section input data file. 5. 20BY40.LIS - the output file for the above sample input file. 6. VAXEFF.COM - A command file to run the linked code on a VAX. 7. VAXEFF1.COM - A second command file called by VAXEFF.COM. Normally, to run this code on a VAX, you simply must compile and link the source code. Note that the program will need to use both input data files, the user data file and the cross section data file. Bryon Anderson bdanders@kent.edu
