This contribution presents the analyses of two-particle femtoscopic correlations of pairs containg deuteron produced in Pb-Pb collisions with energy `sqrt{s_(NNNN)} = 5.02` TeV, that were registered by the ALICE experiment at the LHC. The analyses are based on the femtoscopy technique which allows studying the properties of matter under extreme conditions produced in high-energy heavy-ion collisions. The femtoscopic correlation function depends on both, the properties of the particles emitting source created after the collision and the two-particle final state interactions. In this work there are considered pion-deuteron pairs and preliminary kaon-deuteron pairs. Particles considered in this work are electrically charged hadrons which interact thus via the strong and Coulomb forces. However, neither the parameters describing the strong interaction of both considered particle pairs nor the creation mechanism of (anti)deuterons in heavy-ion collisions are known.The study presented in this contribution contains the methodology of selection of particle samples and the first calculations of the correlation function for these pairs of particles.
