✦ Synopsis

A fast and simple Monte Carlo program is presented that simulates single Bremsstrahlung in Bhabha scattering, e + e--~e + ey, without constraints on scattering angles. This allows the study of this process at arbitrarily small, or even vanishing, scattering angles. Experimental cuts can be imposed on an event-by-event basis, allowing for detailed studies of the process as a limitation to beam lifetimes, or a luminosity-measuring device, in e+ estorage rings. As an application, we show that the easy introduction of a cutoff parameter, corresponding to the characteristic distance between particles in the e± bunches, gives a reduced cross section that is in good agreement with observation.
