Question

1200 particles are to be distributed among three energy levels with energies \(\epsilon_1\), \(\epsilon_2\), and \(\epsilon_3\): \(\epsilon_1 = 1\) eV, \(\epsilon_2 = 2\) eV, and \(\epsilon_3 = 3\) eV. The total energy of the system is fixed at 2400 eV and each possible microstate is equally probable. (a) Assume that the particles are distinguishable. What is the number of microstates? Express your result in terms of \(N_1\), where \(N_1\) denotes the number of particles in the energy level \(\epsilon_1\). What is the most probable value of \(N_1\)? (b) Assume that the particles are identical bosons (quantum particles that are described by a fully symmetric many-body wave function). What is the number of microstates? What is the most probable value of \(N_1\)? Note, even though part (b) mentions the many-body wave function, there is no need to explicitly construct wave functions to answer the questions.
