Abstract
Optical isotope shift measurements have been performed for the fission isomers with low target production rates of employing resonance ionization spectroscopy in a buffer gas cell. Isotope shift ratios and have been measured at the 500.02 nm transition. A difference in the nuclear mean charge radii and an intrinsic quadrupole moment have been deduced, neglecting the nuclear polarization correction. The small difference demonstrates the stability of the deformation if two neutrons are removed.
