K and L x rays induced by 5-MeV/amu α-particle and nitrogen-ion bombardment of ten target elements ranging from Cr to Bi

The K and L x rays from ten target elements from Cr to Bi bombarded by 5-MeV/amu α particles and N ions were measured by a Si(Li) detector. Energy shifts of K x rays and intensity ratios of KβKα, LαLl, LαLβ, LαLγ, and LK were determined by analyzing the experimental results. The ratio of the reduced K-shell ionization cross sections, R_2K, showed a systematic deviation from the Z²₁ dependence.
