摘要：

Cross sections for K-shell ionization have been calculated for light particle (electron, positron) impact. Using a simple correction which takes into account the acceleration of an incident electron by the target nuclear field, we obtain excellent agreement with the available experimental data even at projectile enegies close to threshold. Resonance agreement is also obtaine d with recent measurements for positron impact. © 1990.
