Ru103,105States Observed in the ReactionsRu102, 104(d,p)

The ($d,p$) reaction on ${\mathrm{Ru}}^{102}$ and ${\mathrm{Ru}}^{104}$ has been studied at an incident deuteron energy of 14 MeV. Proton spectra were recorded in a broad-range magnetic spectrograph. Transferred $l$ values and spectroscopic factors were obtained by comparing the measured angular distributions with distorted-wave Born-approximation predictions. The low-lying levels of ${\mathrm{Ru}}^{103}$ are in good agreement with the results of a recent ($d,t$) study; information on higher levels of ${\mathrm{Ru}}^{103}$ and on all levels in ${\mathrm{Ru}}^{105}$ is new. There is good correspondence between strongly excited levels in the two isotopes, although there is evidence of a higher level density in ${\mathrm{Ru}}^{105}$. The summed spectroscopic factors give information on the extent of filling of the neutron orbitals in the targets, and these results are in reasonable agreement with results from the ($d,t$) reaction and for other nuclei in this region.
