On the Continuous Absorption Coefficient of the Negative Hydrogen Ion. II.

In this paper the continuous absorption coefficient of the negative hydrogen ion, determined in an earlier paper (Ap. J., 102, 223, 1945) in terms of the matrix elements of the momentum operator, is further improved to take into account the effect of the static field of the hydrogen atom on the motion of the ejected electron. It is shown that for wave functions for the ground state of H of the forms gen- erally considered, the formula for the absorption cross-section can be reduced to the for
