Charge-Changing Processes in Collisions between Li-like Ions and He2+

By means of a crossed-beams technique the total cross sections for charge transfer and ionization in He2+ + B2+ collisions have been measured at barycentric energies from 10 to 256 keV and from 40 to 240'keV, respectively. Moreover, the angular-differential cross sections for charge transfer at CM energies of 10.18 and 15.3 keV have been determined. The total and differential cross sections are calculated with the Basis Generator Method (BGM) and are in good agreement with the experimental data.
