Description

An ESR study on Fe+ centers in NaCl at sites with various symmetries is presented. Such centers, with axial, octahedral or orthorhombic symmetry, can be observed below 32 K, in crystals freshly quenched at RT, before irradiating at 77 K. On warming to 180 K the conversion of Fe+ (orthorhombic) to Fe+ (axial) occurs. A second conversion of Fe+ (axial) to Fe+ (octahedral) takes place at 220 K. Both conversions are due to the tendency of the positive-ion vacancy to move away from the Fe+ ions. (author)
