Abstract
K-shell x-ray production cross sections were measured for /sub 28/Ni(K) in collision with /sup 1//sub 1/H ions of kinetic energies 55 to 300 keV, /sup 2//sub 1/H ions of 100 to 300 keV, and /sup 4//sub 2/He ions of 200 to 300 keV; for /sub 46/Pd(K) with /sup 1//sub 1/H ions of 215 to 300 keV, and for /sub 47/Ag(K) with /sup 1//sub 1/H ions of 200 to 300 keV. L-shell x-ray cross sections were measured for /sub 47/Ag(L) in collision with /sup 1//sub 1/H ions of kinetic energies 35 to 300 keV, with /sup 2//sub 1/H ions of 60 to 300 keV, with /sup 4//sub 2/He ions of 110 to 300 keV, and for /sub 79/Au(L) with /sup 1//sub 1/H ions of 140 to 300 keV. The collisions conditions were such that the effect of the projectile energy loss during the ionizing collision became significant for the K-shell ionizations, but remained unimportant for the L-shell ionizations. The measurements extend the experimental range of the Coulomb-deflection variable dq/sub 0S/ over previous measurements for the shells S=K by a factor of approx.1.2, and for S=L by a factor of approx.2. This permits a decisive test of current theories for the effectmore » of the deflection of the projectile in the Coulomb field of the target nucleus on inner-shell ionization cross sections.« less
