  The master equation for the cluster-size distribution function is solved
numerically to investigate the electron-hole droplet formation claimed to be
discovered in the direct-gap CuCl excited by picosecond laser pulses [Nagai
{\em et al.}, Phys. Rev. Lett. {\bf 86}, 5795 (2001); J. Lumin. {\bf 100}, 233
(2002)]. Our result shows that for the excitation in the experiment, the
average number of pairs per cluster (ANPC) is only around 5.2, much smaller
than that (10$^6$ typically for Ge) of the well studied electron-hole droplet
in indirect-gap semiconductors such as Ge and Si.
