synonym: perturbed directional correlation spectrometry
acronym: PAC
mentioned: TDPAC, TIPAC
https://doi.org/10.1351/goldbook.08749
Measurement method of gamma-ray spectrometry in which coincidence counting is used for the measurement of parameters describing hyperfine interactions, with internal or external electrical or magnetic field gradients, of the spin of an intermediate level between two gamma-ray transitions in cascade emitted in the decay of a radionuclide.
Notes:
- Perturbed angular correlation spectrometry can be performed both in a time-differential (TDPAC) and in a time-integrated (TIPAC) mode of measurement.
- The parameters describing hyperfine interactions provide information on the chemical atomic environment of the decaying nucleus.
