The influence of various gamma-radiation dose on absorptions of PbO-P 2 O 5 + xMnO 2 (0<x<0.15) vitreous system was monitored by means of electron spin resonance (ESR) and infrared (IR) spectroscopy. Electron spin resonance (ESR) of Mn 2+ ions revealed their distribution as different structural units in P 2 O 5 .PbO 2 glass matrices doped with MnO 2. The absorption line at g eff ≈ 2.0 is prevalent in the spectrum and shows the hyperfine structure (hfs) characteristic of the 55 Mn (I=5/2)fatcat:l4wzjohykjgvdc23zxuahck2c4
