A study of the $^2$H$({\gamma},{\Lambda})$X reaction was performed using atagged photon beam at the Research Center for Electron Photon Science (ELPH),Tohoku University. The photoproduced $\Lambda$ was measured in the $p{\pi^{-}}$decay channel by the upgraded Neutral Kaon Spectrometer (NKS2+). The momentumintegrated differential cross section was determined as a function of thescatting angle of ${\Lambda}$ in the laboratory frame for five energy bins. Ourresults indicated a peak in the cross section at angles smaller thancos$\theta^{LAB}_{\Lambda}$ = $0.96$. The experimentally obtained angulardistributions were compared to isobar models, Kaon-Maid (KM) and Saclay-Lyon A(SLA), in addition to the composite Regge-plus-resonance (RPR) model. BothSLA(r$K_{1}K_{\gamma}$ = $-1.4$) and RPR describe the data quite well incontrast to the KM model, which substantially under predicted the cross sectionat the most forward angles. With the anticipated finalized data on ${\Lambda}$integrated and momentum dependent differential cross sections of$^2$H$({\gamma},{\Lambda})$X~\cite{Kaneta_Beckford}, we present our findings onthe angular distributions in this report.
