Need it ASAP please!
(d) Using the full basis, the system is prepared in a state Va) that is an eigen- function of the lowering operator with eigenvalue a, thus â-|V) corresponding to a superposition: 11.) = e-lal/2 In) n! From the above expression, or otherwise, show that (Valâ+1 1.) = a". Hence, obtain the expectation value of the momentum operator p in this state.
