We report on {pi}-{xi} correlation analysis in Au+Au collisions at {radical}(s{sub NN})=200 GeV and {radical}(s{sub NN})=62 GeV from year 2004 high statistics run of the STAR experiment at RHIC. Correlation analysis of {pi}-{xi} system is presented addressing independently the issue of flow of multi-strange baryons in heavy-ion collisions. We observe effects of both Coulomb and strong interactions in the {pi}-{xi} final state, the latter proceeding via {xi}*(1530) resonant interaction. The technique of spherical harmonics decomposition of the correlation function is used to study space-time separation of the pion and {xi} sources.
