We present theoretical and experimental results for angular and energy distributions ofelectrons emitted in collisions of B2+ with He atoms. In particular, we analyze the cusp formed by projectile Electron Loss to Continuum (ELC) and Electron Capture to Continuum (ECC) . The cusp shape dependence on the electronic initial state is discussed and compared with our previous measurements on Li+ +He. The projectile incident energy was about 414 keV/u and the electron detection angle was varied between 0◦ and 150◦. The experimental data is compared with three-body quantum Continuum-Distorted-Wave calculations.
