Solution of the Two-State Potential-Curve-Crossing Problem

摘要: A general theory of the two-state curve-crossing problem has been developed, with a complete solution an accurate model for "close" crossings (including numerical computations strong coupling). Results clarify position Landau-Zener approximation and its improvements by Nikitin others, provide way extending these approximations into regions often treated incorrectly high-energy limit), can be readily adapted to simple, rapid calculations.
