Homework Statement
A One dimensional box contains a particle whose ground state energy is ε. It is observed that a small disturbance causes the particle to emit a photon of energy hν=8ε, after which it is stable. Just before emission a possible state of the particle in terms of energy eigenstates {ψ1, ψ2...} would be
(a) (√2ψ1-3ψ2+5ψ5)/6
(b)(ψ2+2ψ3)/√5
(c)(-4ψ4+5ψ5)/√41
(d)(ψ1-ψ2)/√2
Homework Equations
Energy eigenvalues for a particle in a 1-D potential well
E=n2h2/8mL2
The Attempt at a Solution
I don't know where or how to start. Can someone help me here? Also if someone could suggest me a textbook with similar problems that would be helpful too...
Thanks
