We report the observation of dipole-forbidden, but quadrupole-allowed, one-photon transitions to high-Rydberg states in Rb. Using pulsed uv excitation of ultracold atoms in a magneto-optical trap, we excite 5s{yields}nd transitions over a range of principal quantum numbers n=27-59. Compared to dipole-allowed (E1) transitions from 5s{yields}np, these E2 transitions are weaker by a factor of approximately 2000. We also report measurements of the anomalous np{sub 3/2}:np{sub 1/2} fine-structure transition strength ratio for n=28-75. Both results are in agreement with theoretical predictions.
