The transition quadrupole moments, $Q_{t}$, of rotational bands in the
neutron-rich, even-mass $^{102-108}$Mo and $^{108-112}$Ru nuclei were measured
in the 8 to 16 $\hbar $ spin range with the Doppler-shift attenuation method.
The nuclei were populated as fission fragments from $^{252}$Cf fission. The
detector setup consisted of the Gammasphere spectrometer and the HERCULES
fast-plastic array. At moderate spin, the $Q_{t}$ moments are found to be
reduced with respect to the values near the ground states. Attempts to describe
the observations in mean-field-based models, specifically cranked relativistic
Hartree-Bogoliubov theory, illustrate the challenge theory faces and the
difficulty to infer information on $\gamma $ softness and triaxiality from the
data.Comment: 17 pages, 4 figure
