| Popis: | The two-photon absorption corresponding to the creation of a large number of biexcitons with zero momentum is studied in CuCl at 4.2 K. The power dependence of the absorption linewidth suggests liquid-like collisions between the biexcitons. The emission spectrum of the biexcitons produced at K =0 is also presented. |
