Consider the Hamiltonian H of a particle in a one-dimensional problem defined by H = P² 2m +V(X) where X and P satisfy [X,P]= ih. Given that H\6) = E, 0): a. Show that (P) =a(0|X|0), where a is a coefficient which depends on the difference between E, and E. Calculate a. (Hint: consider [X, H]) b. From your result in (a), deduce, using the closure (completeness) relation, the equation: 2 (0|P²) =Σ(E-E)||X) m n'
