Why an electron having energy above bound state but below top of the well will have no eigenstate of the Hamiltonian? If it has no such energy eigenstate how can it have energy expectation value? Please Explain.

Why should a high energy electron have to remain in a deep potential well?

Relaxation time is defined as the time taken for mechanical energy to decay to 1/e of its original value. Why do we take a specific ratio of 1/e? What is its significance?
