Abstract
Fast (0.35-1.2-MeV) He- ions produced by double electron capture have been observed in He+-He collisions. The thickness of the gas-jet targe t (4 X 10(13)-10(15) atoms/cm2) has been calculated without any separa te calibration. Single-collision conditions have allowed a direct meas urement of the total cross section of the double electron capture. The se data can be related to the development of theoretical studies on do uble electron capture.
