Abstract

High resolution laser-atomic-beam spectroscopy was applied to study crossed-second-order effects in the isotope shift of the terms 4f75d6s a10D and a8D for151Eu-153Eu. The term dependent effects lead to a difference in the isotope shift of the terms a10D and a8D of 415(20) MHz. The J dependent effects are interpreted through the use of one parameter z5d for each term; z5d(a10D)=41(7)MHz, z5d(a8D)=50(26)MHz.
