Very fast hollow-atom decay processes in Xe30+-C60 collisions.
In Xe30+-C60 collisions at low velocity (0.2 a.u.<v<0.4 a.u.), very fast electron ejection is observed not only for frontal collisions but also for near C60 cage collisions. In frontal collisions, the exit-charge distributions obtained with three projectile velocities are reproduced using a multistep exponential decay model. A mean Auger rate of about 0.4 a.u. is estimated for the decay of hollow atoms during the very short interaction time (<3 fs).
