High-accuracy Rb${}_2^{+}$ interaction potentials based on coupled cluster calculations

Jan Schnabel, Lan Cheng, Andreas Köhn

This work discusses a protocol for constructing highly accurate potential energy curves (PECs) for the lowest two states of Rb${}_2^{+}$, i.e. $X{}^2\Sigma {}_g^{+}$ and $(1){}^2\Sigma {}_u^{+}$,…
