Abstract The OMEGA code calculates the dynamic coincidence solid angles in the CM system for a detector/target arrangement with large illuminated target area or volume and large solid angle for two-particle photodisintegration reactions. The calculation method, based on Monte Carlo simulations, includes the effects of the reaction kinematics, transformations from Lab to the CM systems and rescattering of the secondary particles in the target m... Title of program: OMEGA Catalogue Id: ADNJ_v1_0 Nature of problem The two-particle disintegration of light nuclei by linearly polarized photons is an intensively developing field of Nuclear Physics. Such kind of experiments involves sophisticated processing of the experimental data by software. In particular, the procedure for the extraction of the differential cross section, dsigma/dOmega, from the measured yields of two-particle photodisintegration, involves, in the case of extended targets, a complex evaluation of the average solid angles [1-5], even for si ...
