1. NAME AND TITLE OF DATA LIBRARY
LEP: Cascade and Evaporation Particle Results from Low-Energy Intranuclear Cascade
2. NAME AND TITLE OF DATA RETRIEVAL PROGRAMS
No retrieval program is included in the package.
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.
