  In this paper, we summarize the RXTE measurements of cyclotron resonance
scattering features in 8 accreting pulsars. The wide bandpass and modest
resolution of the RXTE instruments make them ideal for measuring these
generally broad features. In particular, the high energy response of HEXTE
provides a window for discovery of new lines not detectable with proportional
counters such as Ginga or the PCA alone.
