Manuscript Title: BHAGEN-1PH: a Monte Carlo event generator for radiative Bhabha scattering.
Authors: M. Caffo, H. Czyz
Program title: BHAGEN-1PH
Catalogue identifier: ADET_v1_0
Distribution format: gz
Journal reference: Comput. Phys. Commun. 100(1997)99
Programming language: Fortran.
Computer: AlphaVAX DEC 3000 M700.
Operating system: OpenVMS 6.2.
RAM: 1.6M words
Word size: 32
Keywords: Particle physics, Elementary, Event simulation, Bhabha radiative Scattering, Polarized beam, Longitudinal Polarization, Photon emission, Event generator.
Classification: 11.2.

Nature of problem:
The process is measured in e+e- experiments with e- beam longitudinally polarized or not, and is of interest for tests of the Standard Model (QED at low energies), as a background estimation for other processes, and as a radiative correction contribution to small angle Bhabha scattering for luminosity monitoring.

Solution method:
A Monte Carlo event generation with importance sampling method.

Running time:
To generate 10**4 unweighted events are requested 10-20 sec for typical event selection on an AlphaVAX DEC 3000 M700 with OpenVMS 6.2.
