DLC-0012 ZZ-DLC-12D/POPLIB.

1. NAME OR DESIGNATION OF PROGRAM:  ZZ-DLC-12D/POPLIB. A compendium of neutron-induced secondary gamma ray yield and cross section data.

3. NATURE OF PHYSICAL PROBLEM SOLVED

  FORMAT: POPOP-4

  NUMBER OF GROUPS: --

NUCLIDES: H, D, Li, Be, B-10, C, N, O, F, Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Zr, Nb, Mo, Cd, Ba, Eu, Gd, Ta, W, Hg, Pb, U-235, U-238 and Np.

ORIGIN: The library was compiled from the literature and from private files of contributors.

  WEIGHTING SPECTRUM: --

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
The library may be used with POPOP-4 to prepare neutron to gamma- ray group transfer matrices. These can then be merged with multigroup neutron cross section sets (from GAM-2, XSDRN, SUPERTOG,  etc.) and multigroup gamma-ray cross section sets (from MUG, GAMLEG, etc.) to give a cross section set which can be used for coupled neutron and secondary gamma-ray calculations in multigroup transport codes such as ANISN, DOT, DTF-4, and MORSE.
     Data in the library is either

(1) the intensities of secondary gamma rays resulting from neutron-  nucleus interactions (yields), or
(2) the secondary gamma-ray production cross sections for neutron- nucleus interactions (cross sections).
The initial library contains data for H, D, Li, Be, 10-B, C, N, O, F, Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Zr, Nb, Mo, Cd, Ba, Eu, Gd, Ta, W, Hg, Pb, 235-U, 238-U, and Np. Some reactions for which data appear are radiative capture,  fission, inelastic scattering (n,alpha), and (n,p). For many nuclides there are several data sets for a particular reaction.

4. METHOD OF SOLUTION

The library was compiled from the literature and from private files of contributors. No claim is made for the validity of the data.

6. TYPICAL RUNNING TIME

Typical running time of POPOP-4 library TAPE MAKER is less than 2 minutes on the IBM 360/65.

7. UNUSUAL FEATURES: UNUSUAL FEATURES OF THE PROGRAM

8. RELATED AND AUXILIARY PROGRAMS

The retrieval program is referred to as POPOP-4 library TAPE MAKER. The use of this program is described in ref. 2, appendix E.
This program will read a BCD formatted POPOP-4 library tape and make a binary POPOP-4 library tape for use with POPOP-4. In addition the program includes the capability of

(a) making or updating a BCD formatted library tape,
(b) making or updating a binary library tape for use with POPOP-4,
(c) listing any or all the data sets on a library tape,
(d) punching any or all the data sets on a library tape in the
format for use with POPOP-4. (this capability is usually used to retrieve data sets in order to modify the data prior to use with POPOP-4.
