CCRMN — A Program for Calculating Complex Reactions of a Medium-Heavy Nucleus with Six Light Particles

Abstract

The CCRMN program is developed for the theoretical calculation of all complex reactions of a medium-heavy nucleus with a neutron or a charged particle in the 1- to 100-MeV-energy region. In the CCRMN program, the incoming particles can be neutrons, protons, {sup 4}He, deuterons, tritons, and {sup 3}He; the outgoing particles are also the foregoing six particles (corresponding to channels 1 through 6, respectively). In CCRMN, the authors calculate the reactions in the first, second, third, {hor_ellipsis}, up to the tenth emitting processes. In the 1- to 100-MeV-energy region, CCRMN can give correct results for optical model quantities and all kinds of reaction cross sections in first, second, third, {hor_ellipsis}, up to tenth emitting processes. The emitted particles are all the foregoing six particles (channels 1 through 6) in the first, second, and third processes; neutrons, protons, {sup 4}He, and deuterons (channels 1 through 4) in the fourth and fifth processes; neutrons, protons, and {sup 4}He (channels 1, 2, and 3) in the sixth and seventh processes; and only neutrons and protons (channels 1 and 2) in the eighth, ninth, and tenth processes. The output data of CCRMN include the following: the total cross section; the elastic scattering cross sectionmore » and its angular distribution; the total reaction (or nonelastic) cross section; the radiative capture cross section; the (x,x{prime}) reaction and the (x,x{sub 1},x{sub 2}) reaction cross sections, where x, x{prime}, x{sub 1}, and x{sub 2} can be neutrons, protons, {sup 4}He, deuterons, tritons, or {sup 3}He; and {sigma}{sub x,2np}, {sigma}{sub x,3n}, {sigma}{sub x,4n}, {hor_ellipsis}, {sigma}{sub x,10n}.« less
