A new beam line named OEDO which can degrade the beam energy and squeeze the spatial distribution was installed at RIBF. As the first campaign of the experiments, $^{77,79}$Se(d,p)$^{X}$Se reactions were measured as a surrogate of the $^{79}$Se($n, \gamma$)$^{80}$Se* reaction for the nuclear mutation of the radioactive waste of $^{79}$Se. The $\gamma$ transition probabilities from the unbound states of $^{78,80}$Se were determined by directly measuring the outgoing particles instead of detecting the $\gamma$ rays. In this talk, we will explain the experimental setup and the preliminary result on the ($n,\gamma$) cross sections.
