High-resolution doubly differential cross section measurements and calculations for electrons elastically scattered through 180 degree sign from ground-state He- and H-like boron ions are presented covering the entire 1s2lnl{sup '} (for B{sup 3+}) and 2lnl{sup '} (for B{sup 4+}) Rydberg series populated by resonant excitation. The measurements were performed by zero-degree Auger projectile electron spectroscopy of 4-MeV B{sup 3+,4+} ions in collisions with H{sub 2} targets. R-matrix calculations, particularly sensitive at this large scattering angle to electron correlation, exchange, and interference effects, are found to be in excellent overall agreement within the electron-scattering model.
