Description

A new data acquisition method for the time-differential perturbed angular correlation (TDPAC) experiment has been applied to the measurement of electric field gradient in In metal under melting. Combining a 4-detector goniometer with a multiparameter data acquisition system, the temperature of the sample and the time spectrum for each angle are stored event by event in a list mode. The fraction of liquid phase in solid state of In metal has been quantitatively determined as a function of time by this method and the 'hysteresis' has been observed in the course of liquefaction. This technique can be applied to study hyperfine interactions by means of the TDPAC method in high frequency magnetic fields. (orig.)
