The continuous X-ray spectrum refers the range of photon energies produced in an X-ray tube due to the properties of Bremsstrahlung radiation.. The energy of X-ray photons can take a value from zero to the maximum kinetic energy of the incident electrons. Both the continuous X-ray spectrum and the characteristic peaks specific to the absorber will contribute to the total X-ray spectrum.

Request PDF | Reevaluation of the neutron emission probabilities from 241Am-Be neutron source | The neutron emission probability of the ²⁴¹Am–Be neutron source at thermal energies had been The Spectrum Analyzer is used to measure the wavelength spectrum from single shots of the x-ray beam. This is achieved by diffracting a small portion of beam intensity through a grating. The diffracted beam from the grating passes through a curved single crystal. Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, such as in 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 Observations of X-ray spectra for four low-mass binary X-ray sources, Sco X-1, 4U 1608-522, GX5-1 and GX349+2 were performed with the gas scintillation proportional counters on board Tenma.
