Measurement of the three dimensional anisotropic Auger electron emission from excited projectiles can provide the complex amplitudes (magnitudes and relative phases) for the magnetic substates, formed in double electron capture collisions. Done in coincidence with position sensitive detection of the scattered projectiles, one obtains the scattering angle dependences of the complex amplitudes. The first such measurements were reported recently for C{sup 5+} + He collisions; here the authors report on the similar system B{sup 4+} + He at 20 keV collision energy (v=0.27 au). Measurements of this kind are the most detailed available for slow, multiple electron capture collisions. Results will be presented for 1s2s{sup 2} {sup 2}S, 1s2s2p {sup 2}P and 1s2p{sup 2} {sup 2}D terms of B{sup 2+} in comparison with those for the same states of C{sup 3+} formed in the C{sup 5+} + He collision.
