Lawson, Lawson, and Seaton calculated the Born R matrik for H 1s, 2s, and 2p. Using these results thhe transmission matrix was calculnted from T = -- 2iR/(l--iR). Seaton showed that this should give results which are better than those obtained from the Born approximation for the total scattering amplitude. The following cross sections were calculated: elastic (1s--1s, 2s--2s, and 2p-- 2p); momentum loss (1s--1s, 2s--2s, 2p--2p, and 2s--2p); inelastic (1s--2s and 1s- -2pm/sub 1/); and transitions between fine structure levels (2s/sub 1/2/ -2p/sub 1/2/, 2s/sub 1/2/ --2p/sub 1/2/, and 2p/sub 1/2/ -2p/sub 1/2/) . Comparison with experiment showed the results for 1s--2p to be much better than those obtained from the usual Born total amplitude. (auth)
