Collisional ionization has been observed in the collision of electronically excited sodium atoms with potassium atoms. By means of the crossed-beam and stepwise laser excitation technique and time-of-flight measurements, the folowing reactions hnve been invcstigarcd: Penning ionization, Na\* + K -Na

✦ Synopsis
We have performed the first measurement of charge exchange in keV C q ion collisions with Na atoms in their 3s ground 60 state as well as in the laser-excited and aligned 3p state. To interpret the results, we have calculated the correlation diagram of the C q -Na collision system using the Discrete Variational Density Functional Method. Possible channels for electron 60 capture are studied by choosing the collision path along an axis perpendiculax to a pentagon and to a hexagon, respectively.
