In a recent experiment, a gold atom was trapped on a two dimen- sional square surface with an edge length of 50 nm. The surface was flat so that V(x,y)=0. The experiment consisted of observing the emit- ted radiation as the atom slowed down and went into its ground, or lowest energy, state. (a) Write the quantum numbers of the ground state, the first excited state and the second excited state of this system, be sure to indi- cate if each state is degenerate or not. (6 points) (b) What is the energy (in joules) of the photon that will be released when the gold drops from the first excited state to the ground state of this system? (4 points) 2 2.
