We present multi-cut Forced Impulse Method (FIM) cross sections for th
e double ionization of helium by antiprotons in the energy range 12-10
00 keV/amu. These ab initio theoretical cross sections largely reprodu
ce experiments. The necessity of including intermediate dynamic correl
ation in the theoretical description is made manifest. (C) 1997 Elsevi
