Let be the number of particles aligned parallel to H with energy and be the number of particles aligned anti parallel to H with energy . Total energy .
Total number of particles N is given by .
Since density of states is given by , We will find first.

2. Consider an isolated system consisting of a large number N of very weakly interacting localized particles of spin 1 2. Each particle has a rnagnetic mioment μ which can point parallel or anti-parallel to an applied field H. The energy E of the systern is then E =-(ni-n2):1H, antiparallel to H. (a) Consider the energy range between E and E+δΕ where δΕ < E but is microscopically large so that δΕ μΗ. What is the total number of states...
