Homework Statement
A particle of mass m is confined in a one dimensional well by a potential V. The energy eigenvalues are
[tex]E_{n}=\frac{\hbar^2n^2\pi^2}{2mL^2}[/tex]
and the corresponding normalized eigenstates are
[tex]\Phi_{n}=\sqrt{\frac{2}{L}}sin(\frac{n\pi x}{L})[/tex]
At time t=0 the particle is in the ground state. Find the probability that the particle is between x=0 and x=L/6.
Explain why this probbility does not depend on time.
Homework Equations
The Attempt at a Solution
I have found the probability to be [tex]\frac{1}{6}-\frac{\sqrt{3}}{4\pi}[/tex]
My question is why the probability does not depend on time. Is it because the particle is in the ground state?
