P. Corvisiero et al., SIMULATION OF PHOTON NUCLEON-INTERACTIONS .1. AN EVENT GENERATOR FROMTHE PION THRESHOLD UP TO 4 GEV, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 346(3), 1994, pp. 433-440
We describe an event generator that reproduces the photon-nucleon inte
raction from the pion threshold up to 4 GeV accounting to a large exte
nt for the total photoabsorption cross section. Many reaction channels
on the nucleon have been considered: namely single pion production, e
ta production, multipion production and some hyperon production channe
ls. Compatibility with the GEANT and PAW software packages has been as
sured throughout. The extension to reactions on two and three nucleon
systems is discussed.
