AbstractA new type of time-dependent Mossbauer spectroscopy is proposed and realized on the basis of using the two-step decay (119m)Te --> 113Sb --> Sn-119. For the GaAs samples, implanted with a dose of 110-keV (119m)Te + 10(15) stable Te/cm2 and annealed at 600-degrees-C, the relative intensities of various lines of the Mossbauer spectra have been measured as functions of xi, a parameter being equal to PHI-Te/PHI-Total; by definition xi itself is determined from the annealing time t(a), the initial time t(i) and the final time t(f) of the measurement of each spectrum. This kind of time-dependent Mossbauer spectroscopy can be used to investigate the change of the environment of the probe atoms in solids. The lines of the Mossbauer spectra have been identified. The problem of the environmental change of Te atoms in GaAs after their decay into Sb and the mechanism of nonsubstitutional Te have been discussed. Our experimental results are also compared with previous data taken from Mossbauer spectra of Te-125 and Te-129 in GaAs.
