Polynomial representation of the bremsstrahlung spectra of a thick target for electrons of energy 10-22 MeV

A method is presented which may be used to represent bremsstrahlung spectra in a different energy range and for targets of different composition. The authors represent in polynomial form the set of bremsstrahlung spectra for targets used on the MT-22 microtron of the Laboratory of Nuclear Reactions, JINR, which consist of 0.2 cm tungsten and 3 cm aluminum. Bremsstrahlung spectra are shown for the electron energies, together where E /SUB e/ is the mean electron energy in the beam f(Ee - Ee) is the form of the electron energy distribution in the beam. In the simplest case, the authors say, it may be regarded as Gaussian.
