Program for computer simulation on photoproduction of mesons decaying into two photons

Experiments carried out using multi-detector arrays and wide-band taggers in general lead to large amounts of data which can only be meaningfully analysed if the experiment is accompanied by detailed computer simulations, being at least ten times as precise as the result of the experiment. For this reason we have developed a computer code for the simulation of photoproduction of mesons decaying into two photons which avoids Monte-Carlo procedures, and have applied this code to studies of possibilities to separate events of proton Compton scattering from events of the p(γ, π0)p reaction. Requiring only a very moderate computer time, our new code leads to predictions of photon spectra and angular distributions of recoil protons without the fluctuations typical for a Monte Carlo result.
