The MeV carbon cluster ions provided by 1.7 MV tandem accelerator were identified and Rutherford backscattering spectra of MeV carbon cluster ions on the gold film were measured with silicon surface barrier detector.
The thick targets of Ti,Fet Ni and Zn have been bombarded with 3 to 7Me V nickel ions.The X-ray spectra of the projectiles and targets showed a significant difference in the intensity of the X-ray radiation for severa...The thick targets of Ti,Fet Ni and Zn have been bombarded with 3 to 7Me V nickel ions.The X-ray spectra of the projectiles and targets showed a significant difference in the intensity of the X-ray radiation for several targets.The explanation of this phenomenon by quasimolecular orbital energy level correlation diagrams and the possible application of Ni ion induced X-ray emission were discussed.展开更多
