Abstract

Nuclear magnetic dipole and electric quadrupole moments and changes in mean square charge radii for the neutron-rich155–159Eu isotopes have been measured using resonance ionization spectroscopy at the IRIS facility. It has been found that the isotopes withN>92, unlike the isotopes with 89≦N≦92, have an ordinary character of odd-even staggering in nuclear charge radii. This means that the octupole deformation attributed previously to the europium nuclei around154Eu does not display itself in the charge radii of heavier europium isotopes.
