Gamma-ray spectroscopy is the qualitative study of the energy spectra of gamma-ray sources, such as in the nuclear industry, geochemical investigation, and astrophysics. Gamma-ray spectrometry , on the other hand, is the method used to acquire a quantitative spectrum measurement.
A gamma-ray spectrometer (GRS) is an instrument for measuring the distribution (or spectrum—see figure) of the intensity of gamma radiation versus the energy of each photon. The study and analysis of gamma-ray spectra for scientific and technical use is called gamma spectroscopy , and gamma-ray spectrometers are the instruments which observe ...
The technique of measuring the gamma radiation with good efficiency is known as total absorption spectroscopy. The pandemonium effect concerns the difficulty in using high resolution detectors in beta decay experiments, to construct a complex level scheme.
Gamma rays were first discovered and studied in 1900 by a French chemist, Paul Villard while observing radiation from radium. [6] However, the first quantitative analysis of gamma radiation is credited to Rutherford and Andrade in 1914. This earliest technique was accomplished by diffraction spectroscopy using a rock-salt crystal. [16]

The perturbed γ-γ angular correlation, PAC for short or PAC-Spectroscopy, is a method of nuclear solid-state physics with which magnetic and electric fields in crystal structures can be measured. In doing so, electrical field gradients and the Larmor frequency in magnetic fields as well as dynamic effects are determined.
