7. Consider a system that may be unoccupied with energy zero or occupied by one particle in either of three states, one of energy +e and one of energy -e and one of zero energy. (a) If we assume that there is a maximum of one particle, show that the grand partition function for this system is Z=1+1+Xexp(€/kbT) + Xexp(-e/kBT), where l is related to the chemical potential u by 1 = exp(u/kbT).

multiple choice
An electron in a certain atom could move from the ground state (E=E_O) 10 points to the first excited state (E=E_1) inside an infinite well by absorbing photon with wavelength 1. If while in this excited state a photon the wavelength N2 is sent to the electron to be absorbed, to which energy state will the electron move? (Hint: energy of a photon is given by E=hf=hd where c is the speed of light) O E 2 O...
