Abstract
The free-free absorption coefficient of the negative hydrogen ion is calculated in both the length and velocity formulations using the method of polarized orbitals to describe the free electron. The bound-free cross section of Bell and Kingston (1967) is converted to an absorption coefficient and combined with the present free-free results. Comparison with other calculations and the use of certain oscillator strength sum rules suggests that the total H- absorption coefficient values of the present paper are accurate to better than 10%.Keywords
