Optical Transitions and Charge-Exchange in Highly Charged Quasi-Molecules

Figure 4

The two alternative evolutions of the diabatic energy terms 𝑉₁₁ and 𝑉₂₂ (the dashed lines) with respect to 𝑥 (dimensionless distance), within the Nikitin’s model [25]. The solid lines stand for the adiabatic energy terms. The energies are in arbitrary unit, and Δ𝜀 is the splitting between the terms at large distances. Case (a): intersecting diabatic terms. Case (b): nonintersecting diabatic terms.
