Asolid contains n mutually noninteracting nuclei of spin 1. each nucleus can therefore be in any of three quantum states labeled by the quantum number m, where m = 0, ±1. due to the electric interactions with the internal fields in the solid, a nucleus in the state m = 1 or in the state m = 1 has the same energy " > 0, while its energy in the state m = 0 is zero. (a) write the partition function in a canonical ensemble for this system of n nuclei
