Studies of the $\mathrm{^{19}O(d,p)^{20}O}$ reaction at {\sc resolut}

The energetic location of the d$_{3/2}$--orbital in neutron-rich nuclei is of particular interest as it determines the location of the drip-line in the oxygen isotopes. Its behaviour has recently been discussed as a consequence of three-body forces\footnote{T. Otsuka et al., Phys. Rev. Lett 105, 032501 (2010)}. Manifestations of such forces are traced through the location of the d$_{3/2}$ orbital, which closer to stability leads to highly excited states. In order to study the location and fragmentation of this orbital in $^{20}$O, we performed an experiment at the {\sc resolut} radioactive beam facility of the Florida State University accelerator laboratory. We produced a beam of the short-lived $^{19}$O isotope with an intensity of $1 \times 10^5$ pps, 65$\%$ purity and 4.11 MeV/u. This beam was used to study the spectroscopic factors of bound and unbound states of $^{20}$O using the $(d,p)$ reaction in inverse kinematics and components of the new {\sc anasen} detector array. We will present the methods used and the first results of this experiment regarding the spectroscopic factors of unbound d$_{3/2}$ resonances in $^{20}$O.
