Abstract
The process
is highly suppressed when the total angular momentum of the two colliding photons is zero so that it cannot be used for luminosity determination. This configuration, however is needed for Higgs production at a photon collider. It will be shown that the process
can be used in this case to measure the luminosity of a collider with a precision that is good enough not to limit the error on the partial decay width
