Abstract
Using thick targets the continuous X-ray spectra arising in the collision systems Al+p (0.5–7 MeV), Si+p (0.6–6 MeV), Si+14N (6 MeV, 14 MeV), Ti+p(1 MeV) and Ti+14N (14 MeV) were measured by means of a Si(Li) detector. Total yields were derived and compared with numerical results of calculations for secondary electron and nuclear bremsstrahlung. For Si and Ti the continuous spectra from one and the same target bombarded with protons and14N ions of equal velocity were investigated. Drastic deviations from theZ 21 scaling have been found. They could be attributed to contributions of MO radiation originating by recoil of target atoms. The influence of characteristic line profiles on the measured spectra is also discussed.
