2.2.3.- X-ray diffraction
... The x-ray spectra were obtained in a step-scan mode. This means that the sample and the detector rotated in steps instead of in a continuous way. The appropriate step size for each experiment was selected in order to have at least 10 experimental points above the half height width. Therefore, depend ...

Alpha Decay
... The alpha particle is a helium nucleus (2protons, 2 neutrons) produced from the radioactive decay of heavy metals and some nuclear reaction. The high positive charge (2+) of an alpha particle causes electrical excitation and ionization of surrounding atoms. Alpha particles are the least penetr ...

Gamma spectroscopy
Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, in such as the nuclear industry, geochemical investigation, and astrophysics. Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced. A detailed analysis of this spectrum is typically used to determine the identity and quantity of gamma emitters present in a gamma source, and is a vital tool in radiometric assay. The gamma spectrum is characteristic of the gamma-emitting nuclides contained in the source, just as in optical spectroscopy, the optical spectrum is characteristic of the material contained in a sample.
