1. NAME AND TITLE OF DATA LIBRARY

MEP: Cascade and Evaporation Particle Results from Medium-Energy Cascade Calculations.

2. NAME AND TITLE OF DATA RETRIEVAL PROGRAMS

No retrieval program is included in the package.

3. CONTRIBUTOR

Oak Ridge National Laboratory, Oak Ridge, Tennessee.

4. HISTORICAL BACKGROUND AND INFORMATION

MEP is an extension to higher energies than those described in DLC-1/LEP, i.e., it gives results pertaining to the nonelastic interaction of high energy (E < 3 GeV) protons, neutrons, pi+ and pi- mesons on complex nuclei.

MEP represents output from running Analysis Codes I and II and EVAP, operating on data generated by MECC-7, all of which are auxiliary routines in the Medium-Energy Intranuclear Cascade Code System packaged as CCC-156/MEP in the RSIC Computer Code Collection.

This data library is identical to the one which was earlier packaged as DLC-17/MECC-7.

5. APPLICATION OF THE DATA

The data can be used in the calculation of the penetration of energetic protons, neutrons, pi+ or pi- mesons on thick shields. It provides the necessary information pertaining to the properties of the secondary particles that are emitted when the particles that are being transported through the shield collide with the nuclei of the elements of the shield.

The data can also be used in the design of experiments where thin targets are used and counting rates and backgrounds must be estimated, and it can be used in the theoretical interpretation of many of the results in these experiments.

6. SOURCE AND SCOPE OF DATA

The source of the data is the MECC-7 code (packaged in CCC-156/MEP). The nonelastic interactions considered are for incident protons and neutrons with energies ranging from 0.5 to 3 GeV and pi+ and pi- mesons with energies from 0.5 to 2.5 GeV on:

16O, 27Al, 65Cu, 100Ru, and 207Pb.
