Use the semi-infinite-well potential to model a deuteron, a nucleus consisting of a neutron and a proton. Let the well width be 3.5 10-15 m and V0 - E = 2.2 MeV. Determine the energy E.
How many excited states are there?
What are their energies? (If an excited state doesn't exist, enter a value of zero.)
