Cross sections for single and double ionization of atomic helium under impact by fast multiply charged ions

Expressions for the cross sections for single and double ionization of atomic helium in collisions with fast multiply charged ions are obtained in the collision parameter range υ 2≫Z≳υ, υ 0<c, where Z and υ are, respectively, the ion charge and ion velocity, υ 0 is the characteristic velocity of electrons in the atomic helium ground state, and c is the velocity of light.
