Eigen energies

  1. Dec 24, 2009 #1
    just a question about the energies associted wuth the schrodinger equation> are the energy values always positive values. I thought that since when the eigenfunctions exist the particle is in a bound state, that the energy should be less than that required to escape a bound state and should be negative.

    Yes, the energies can be negative. However, there must exist a lowest energy eigenvalue, otherwise the system could lose an infinite amount of energy.
