The high-frequency limit of the bremsstrahlung spectrum from very high- energy electrons was calculated exactly with numerical methods. It is found that, even in the heaviest elements, oniy the s- and p-state partial waves of the outgoing zero-energy electron contribute significantly to the cross section: for Th(Z = 90) the s state gives 56~ of the total and the p state 42%, while the d- state contribution is 2% and the f-state contribution 0.1%. It is also found that the s- and p-state cross sections are well represented by analytic expressions that were given previously. (auth)
