Title:	Calculations of charge-transfer in U92+ - U91+ collision using the finite basis set of Hermitian B-splines on a lattice in coordinate space
Abstract:	Calculations of the charge-transfer probabilities in low-energy collision of U92+ (as a projectile) and U91+ (as a target) are presented. The method is based on numerical solving the time- dependent two-center Dirac equation using the finite basis set of Hermitian B-splines on a lattice in the Cartesian coordinate system. The motion of the nuclei is treated classically. Starting with the 1s1/2 target state, the electron wave function is calculated for all subsequent time points. The final wave function contains the whole information about the process we are interested. The charge- transfer probabilities are calculated at the projectile energy Elab = 6 MeV/u for various values of the impact parameter. The results of the calculation are compared with the previous calculations by other authors [1], who used a rather similar method, and with our recent results [2] obtained within the approach employing atomic-like Dirac-Sturm orbitals, localized at the ions. We consider this work as a new step towards investigations of the quantim dynamics in heavy ion collisions near the supercritical regime (see, e.g., Ref. [3] and references therein).
