Abstract
Single crystals of RbKBrCl are grown by the melt growth technique and irrad iated using the Ni-38(7+) ion beam of 100 MeV energy. A single line electro n paramagnetic resonance spectrum has been observed for single crystals irr adiated with the dose of 10(14) ions/cm(2). This spectrum shows an angular separation of 10 gauss between maximum and minimum g positions on crystal r otation. A decrease in intensity of the EPR line with time is observed. ne radical produced is identified as an electron centre which is tied to the l attice.
