• The ESR spectra and the optical absorption spectra of 7-irradiated MgCI,single crystals, which have a layer ionic crystal structure, have been investigated.For a commercial reagent grade single crystal, an optical absorption band isfound at about 3.35 eV, and a single broad magnetic resonance band in the ESRspectrum at y=2.0009 40.0009, whose width is 50 -5,5 G. From the measurementsof the isothermal decay curves of these bands, it is found that these bands originatein the same lattice defect. An trapped electron center is proposed for a model ofthis defect. In a sample made by recrystallization of a com?nercial crystal, fourhyperfine structure lines are found in the ESR spectrum. By assuming an axialsvmmetrv, the values of ozz=2.50-E0.08, on =2.29:110.05, .4//=4600:l-900 MHzand .4m=1400i-500 Ml-Iz are obtained and Cl' c:enter is rror>osed as a model.
