Abstract
Self-trapped holes of the forms of Br0 and Br2- are stable in (NH4)2Ag Br3 irradiated by gamma-rays at 77 K. These sorts of self trapped hole s are the analogues of those in (NH4)2AgI3. It is Common in alkali or ammonium silver halides that (halogen)0 is stable at 77 K. The Br0 dec ayed at 160 K in an annealing process. The Br2- was converted into ano ther form of Br2- at 250 K, which decayed at 310 K.
