We report a new measurement of the exclusive $$e^+ e^- to D^{(*) pm} D^{*mp}$$ cross sections as a function of the center-of-mass energy from the $$D^{(*) pm} D^{* mp}$$ threshold through $$sqrt{s}=6.0$$ GeV with initial-state radiation. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of $$951$$ fb$$^{-1}$$. The accuracy of the cross section measurement is increased by a factor of two over the first Belle study. We perform the first angular analysis of the $$e^+ e^- to D^{* pm} D^{* mp}$$ process and decompose this exclusive cross section into three components corresponding to the $$D^*$$ helicities.
