Absolute cross sections for the production of ${\mathrm{H}}^{-}+{\mathrm{D}}^{+}$ in the collision of cold ${\mathrm{HD}}^{+}$ with electrons have been measured in the storage ring CRYRING at Manne Siegbahn Laboratory, Stockholm University in Stockholm. The magnitude of this cross section $(\sim 3\times {10}^{-19}\hspace{0.5em}{\mathrm{cm}}^2$ above threshold), as well as its interference pattern (14 peaks in the interaction energy region 0–16 eV) were found to be identical to that observed for the production of ${\mathrm{D}}^{-}+{\mathrm{H}}^{+},$ which was measured earlier in CRYRING.
