Ionization of the helium atom by slow electrons was computed by neglecting exchange and by taking into account only the s-wave for the incident and atomic electrons. The coulombic wave function of the electron was replaced by the first term of a Bessel series. An expression was obtained for the effective ionization cross section, and the computations were carried out on a digital computer. The calculated cross sections for the single ionization of the helium atom lie below the experimental values, and belowv the values of GeltNoneman reported in Phys. Rev., 102: 171 (1956). (TTT)
