Calculate the ground state energy of a helium atom in a box of 1cm on a side. Solution: these are constants that we will see again and again. I set c = 1. In the ground state = 3, the helium mass is about 4 times the proton mass, and using , the energy is roughly E = [4(10^6)10(3)]/[2(4)(10^9)(10^16)] ~ 1.5 x 10^(-18) ev. This is a small energy, especially when compared to room temperature energy of .025 ev. You...

Using time dependent perturbation theory, estimate the ratio of the probability of a transition to a 3p orbital compared to that to a 2p orbital when a hydrogen atom in its ground electronic state is exposed to 105nm light for 1 femptosecond. What is the ratio for a 2 femptosecond exposure? Explain the difference. (Hint: orbital functions in addition to energy differences need to be considered; an integral table is also helpful)
