Abstract
Fast (r < 2 ns) short-wavelength emissions have been detected overlapp ing the continuous intraband luminescence on exciting KBr, RbBr, KCl a nd RbCl crystals by an electron beam. These emissions are attributed t o the radiative decay of metastable one-halide self-trapped excitons. The weak 5.8 eV emission can effectively be excited in a KBr crystal i n the region of the formation of excitons (6.73-7.3 eV).
