Abstract
Laser resonance ionization spectroscopy was performed on the rare einsteinium isotopes at the RISIKO mass separator in Mainz. With low sample sizes ranging down to femtograms, the prominent 352 nm-ground-state transition was measured in all three einsteinium isotopes, and four additional ground-state transitions were measured in . Hyperfine-structure analysis resulted in assigned spin values of and . From the extracted coupling constants, nuclear magnetic dipole moments of and as well as spectroscopic electric quadrupole moments of and were derived. Our value for deviates from the value of extracted from the angular anisotropy of -radiation emitted by .
