摘要：

The cross section for the process gamma gamma --> B-c(B-c*)(b) over bar c is calculated. It is shown numerically that the fragmentation mechanism of B-c production is not realized at any energies and that, near the threshold, the production of the pseudoscalar state is strongly suppressed in relation to the production of the vector state. A method is used in which the direct calculation of the amplitudes of the corresponding subprocesses by means of a FORTRAN program is followed by numerical Monte Carlo integration over the phase space.
