The mobility of electrons in specially purified AgCl crystals at high electric field has been investigated in order to clarify the scattering mechanism of fast electrons in ionic crystals. A fast-pulse technique was adopted to observe both the transient photoconductivity and the Hall mobility for photoelectrons. The experimental results show that the mobility of fast electrons at low temperatures is a decreasing function of electric field. An energy dissipation mechanism similar to the scattering due to the acoustical mode of lattice vibration is suggested for these fast electrons.
