WebNov 8, 2024 · Transitional States. Let's start by refreshing our memory that a general quantum state can be written – using the completeness relation – as a linear combination of stationary states ( Equation 2.4.14 ): Ψ(t) = ∑ n Cn En e − iEn ℏt. Technically, we need to include all the quantum numbers in the linear combination.
