The majority of measurements assessing the source properties are based on identical particle pairs, providing direct access to the characteristics of the single-particle source. The work in this paper demonstrates, via femtoscopy measurements of charged pion--deuteron pairs in Pb--Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$~TeV, the feasibility of accessing the characteristics of the single-particle femtoscopic source by using particle pairs with large mass differences such as pions and deuterons. The first experimental results of the measurement of deuteron source sizes in ultrarelativistic heavy-ion collisions are presented. The results show good agreement with the trend derived from other charged hadrons such as pions, kaons, and protons as a function of transverse mass, indicating similar source properties.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.166737.v1/t1","@type":"Dataset","description":"pion-deuteron (same charge) correlation function for centrality 0-10% from Pb-Pb
