Observation of Nuclear Bremsstrahlung by Bombardment of Thick Cu and Nb Targets with exp 14 N Ions of 14 and 27 MeV

摘要

By use of thick Cu and Nb targets, the continuous X-ray spectra arising from bombardment with exp 14 N ions (14 MeV, 27 MeV) were measured. A Ge(Li) X-ray detector positioned at theta/sub lab/ = 90 exp 0 with respect to the beam direction was applied. The experimental data were compared with results of numerical calculations for nuclear bremsstrahlung, taking into account the interfering E1 and E2 components of this radiation. For ion energies of 14 MeV experimental and numerical results agree within the experimental errors. For 27 MeV incidence energy one obtains deviations, which are attributed to Compton continua of scattered gamma -ray quanta emitted by the target and the beam line system as a result of nuclear reactions.
