Phys. Rev. A 75, 032521 (2007) [4 pages]Nuclear polarizability of helium isotopes in atomic transitionsReceived 14 December 2006; published 28 March 2007 We estimate the nuclear polarizability correction to atomic transition frequencies in various helium isotopes. This effect is non-negligible for high precision tests of quantum electrodynamics or accurate determination of the nuclear charge radius from spectroscopic measurements in helium atoms and ions; in particular it amounts to 28(3) kHz for 1S-2S transition in 4He+. © 2007 The American Physical Society URL:
