Abstract
Isomer shifts of the → rotational transition in were determined in Mössbauer measurements. From comparison with isomer shifts in and , the ratios and are deduced. These ratios imply a considerable increase in rigidity for deformed nuclei above neutron number . The existing theoretical values are discussed.
