RSIC DATA LIBRARY DLC-001


1. NAME AND TITLE OF DATA LIBRARY

LEP: Cascade and Evaporation Particle Results from Low-Energy Intranuclear 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

This is the first library of its kind pertaining to the nonelastic interaction of energetic protons, neutrons, pi+, and pi- mesons on complex nuclei. It represents output from running Analysis Codes I and II and EVAP, operating on data generated by LECC-15, all of which are auxiliary routines in CCC-47/LEP (Low-Energy Intranuclear Cascade Code System).

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 code LECC-15 (packaged in CCC-47/LEP). The nuclear model and physical assumptions incorporated in LEP are described in Hugo W. Bertini, Phys. Rev. 131, (1963) 1801, with erratum, Phys. Rev. 138 (1965) AB2. The nonelastic interactions considered are for incident protons and neutrons with energies varying from 25 to 400 MeV and pi+ and pi- mesons with energies ranging from 25 to 300 MeV on:

12C, 16O, 27Al, 52Cr, 65Cu, 100Ru, 190Ce, 184W, 207Pb, 238U.

The type of information available from these reactions is described in detail in the documentation included in the package for DLC-1/LEP and in Hugo W. Bertini, Nucl. Phys. 87 (1966) 87.
