Nuclear moments and isotope shifts of europium isotopes by hyperfine structure investigations with collinear laser — Ion beam spectroscopy

Hyperfine structures and isotope shifts of the transition 4f7(8S 7 2/0 )6p3/2 (7/2,3/2)4−4f7(8S 7 2/0 ) 5d9D 4 0 ,λ=604.95 nm, of stable151Eu and153Eu and radioactive152Eu and154Eu have been investigated by collinear laser — ion beam Spectroscopy. Nuclear quadrupole moments have been derived.
