Measurement of the gamma ray spectrum provides information about the chemical state of the iron atom in the sample.
2.
Another advantage of using a gold tamper and lining is that neutron capture events generally form MeV, which is in the hard x-ray to gamma ray spectrum.
3.
The ART-S spectrometer covered the X-ray energy range while the KONUS-B and TOURNESOL experiments covered both the X-ray and gamma ray spectrum.
4.
One of the key difficulties of harnessing the energy from matter-antimatter collisions is that most of the energy released by them is in the X-ray and gamma ray spectrum.
5.
Because of their well-defined energy ( 511 keV ) and characteristic, Doppler-broadened shape, annihilation radiation can often be useful in defining the energy calibration of a gamma ray spectrum.
