Description

Isotope shift measurements have been performed for the 242fAm fission isomer with target production rates of only a few per second. The method is based on resonance ionization spectroscopy (RIS) in a buffer gas cell with radioactive decay detection of the ionization process (RADRIS). A relative isotope shift ratio Xexp=IS242f,241/IS243,241=41.7±0.9 has been measured for the 500.02 nm transition corresponding to a nuclear parameter A242f,241=(5.4±0.3) fm2. A preliminary analysis of the quadrupole moment based on the deformed Fermi model of the nuclear charge distribution results in Q20=35.9±1.1(+0.3-0.7) model eb
