Abstract

Synopsis We investigate ultracold collisions of heteroisotopic pairs of Ca with Ca+ mediated by an external magnetic field. Based on the nuclear spin of Ca, namely I = 7=2 for ⁴³Ca and I = 0 for other isotopes, we identify different scattering dynamics and characterize magnetic Feshbach resonances in ⁴³Ca+⁴³Ca+ and ⁴³Ca+(40;42)Ca⁺ collisions. Our results suggest that interisotopic Feshbach resonances could be used to control charge-exchange in ultracold atom-ion mixtures of Ca and its ion.
