Abstract

Using a particle-photon coincidence technique, we have measured the influence of the solid target preparation and thickness on the target K-vacancy production probability (P_K(b)) in collisions of 3.6 MeV/u Ni²³⁺ with Ge. The probabilities were measured as a function of the impact parameter b which is calculated from the projectile scattering angle using a screened Bohr-type potential. For target thicknesses varying by more than a factor of 100, no change in the shape of the P_K(b) curve was found. Even the data obtained with implanted Ge targets (≈ 1 x 10¹⁶atoms cm^-2), used for the first time in an L-K vacancy-transfer experiment, showed the typical solid target behaviour with the adiabatic peak being shifted towards smaller impact parameters.
