The twofold diabatization of the KRb $(1\sim 2{)}^1\Pi$ complex in the framework of \emph{ab initio} and deperturbation approaches

S. V. Kozlov, E. A. Pazyuk, A. V. Stolyarov

We performed a diabatization of the mutually perturbed $1^1\Pi$ and $2^1\Pi$ states of KRb based on both electronic structure calculation and direct coupled-channel deperturbation anal…
