	Gamma Ray Spectroscopy
		Many radionuclides can be identified by examining the characteristic gamma rays emitted in the decay of the radioactive "parent" to a "daughter" nucleus.
		A count at CE2 corresponds to an event in which a single gamma ray: (a) enters a detector with 1.275 MeV, (b) reverses its direction completely in a Compton backscattering collision with an electron in the detector, and (c) exits the detector volume without further loss of energy.
		The energy lost by the backscattered gamma ray is transferred to the recoiling electron which slows in the detector, producing the observed signal.

	GAMMA SPECTROSCOPY
		Gamma spectroscopy is a radiochemistry measurement method which determines the energy and count rate of gamma rays emitted by radioactive substances.
		A detailed analysis of the gamma ray energy spectrum is used to determine the identity and quantity of gamma emitters present in a material.
		The output is a plot of pulse height and gamma activity, as shown in Figure 28.

	Nuclear Structure Research at Argonne
		Discrete line spectroscopy investigates the cold SD bands and tries to determine their properties, in particular the nature of the excitations in the SD well.
		The spectra, which have a quasicontinuous distribution with superimposed broad structures and sharp peaks, establishes the decay mechanism as due to mixing of a SD state with some of the sea of normal states in which it is embedded.
		We propose that a conspicuous clustering of gamma strength between 1.4 and 2.2 MeV is due to a rearrangement of the level densities by pair correlations.

	Exp 30: Gamma Ray Spectroscopy with a Germanium Detector
		Some calibration gamma ray energies are given in Table 1; the energies and intensities of other lines can be found in the CRC Handbook of Chemistry and Physics or in the Table of Isotopes.
		The spectrometer is calibrated using the high and low energy gamma rays of the three, and then the energy of the middle gamma is then measured.
		Gamma rays may also be produced if the final state nucleus is unstable and decays by beta or alpha emission.

	Gamma Ray Spectroscopy
		To gain experience in the interpretation of gamma ray spectra for the purpose of identifying gamma ray emitting isotopes.
		Gamma ray emitters can be identified by measuring their emitted gamma ray energies and correlating them with standards.
		Finally, be sure to return all gamma sources to their proper containers, and place them in the provided storage location.

		Spectroscopy is a technique that uses the interaction of energy with a sample to perform an analysis.
		A spectrum is a plot of the intensity of energy detected versus the wavelength (or mass or momentum or frequency, etc.) of the energy.
		In simplest terms, spectroscopy requires an energy source and a device for measuring the change in the energy source after it has interacted with the sample (a spectrophotometer or interferometer).

		Dating studies on palaoeanthropological sites is usually carried out on material associated with the human remains, such as the sediment, charcoal or other fauna rather than the human specimen itself.
		As a consequence, all the older fossils could not be analysed and many important questions in our understanding of human evolution could not be addressed.
		Although gamma spectrometry is the least efficient method for measuring isotopes of the U-decay chains, it is completely non-destructive.

	Natural Gamma Spectroscopy Probe
		The natural gamma spectroscopy probe analyses the energy spectrum of gamma radiation from naturally occurring or man-made isotopes in the formation surrounding a borehole.
		The probe normally operates in ‘fixed window’ mode, using five preset energy windows to determine concentrations of the main natural emitters, potassium, uranium and thorium as continuous measurements.
		Gamma photons produced by decay of naturally occurring potassium, uranium, thorium and/or unstable man-made isotopes in the formation strike are detected by a large-volume gamma scintillation counter and converted to electrical pulses.

	Peaks in gamma spectroscopy (Site not responding. Last check: 2007-10-14)
		Radionuclides emit gamma rays at fairly speicific energy corresponding to particular transitions in the nucleus.
		The peaks, assuming one means the large peaks, are from those characteristic gamma rays.
		For some radionuclides which have energies greater than 1.12 MeV, the gamma ray may interact with a nucleus (nuclear field) and a positron-electron pair may be formed.

	PSR-0154: GAMIDENT, Aid Identification of Unknown Materials by Gamma-Ray Spectroscopy
		DESCRIPTION OF PROGRAM OR FUNCTION - The gamma rays emitted by an isotope undergoing radioactive decay or neutron capture have energies and intensities that are characteristic of that isotope.
		Such a set of gamma rays is often referred to as the signature of the isotope.
		A useful method for the nondestructive assay of unknown materials is based on identifying the signature of the isotope.
