Production of (2s/sup 2/)/sup 1/S, (2p/sup 2/)/sup 1/D, and (2s2p)/sup 1/P states by double electron capture in 150--500-keV /sup 3/He/sup 2+/+He collisions

The production of (2s/sup 2/) /sup 1/S, (2p/sup 2/) /sup 1/D, and (2s2p) /sup 1/P states formed by double capture into projectile autoionizing states was measured with high resolution using 0/sup 0/ Auger spectroscopy in 150--500-keV /sup 3/He/sup 2+/+He collisions. Absolute cross sections for these states were determined to lie approximately between 10/sup -18/ and 10/sup -21/ cm/sup 2/, the production of the (2s/sup 2/) /sup 1/S state being dominant. An extension of a continuous distorted-wave independent-particle model to the calculation of double-electron-capture cross sections was found to overestimate our results by a large factor, ranging between 6 and 75.
