Phys. Rev. A 37, 4207–4212 (1988)Measurement of isotope shifts of two-photon transitions in berylliumReceived 26 August 1987; published in the issue dated June 1988 We have measured 10Be:9Be isotope shifts in the 1S and 1D Rydberg series by resonance-ionization mass spectrometry. Pronounced interference of exchange and correlation contributions to the isotope shift is observed in the 1D series, reflecting strong interaction of 2snd and 2pnp channels. The finite-mass correction to the ionization energy of 10Be is inferred to be 270±40 MHz. © 1988 The American Physical Society URL:
