A statistical system is composed of N particles with spin 1 2 ,
immersed in a magnetic field H. The particles are fixed in their
positions and possess a magnetic moment µ. The Hamiltonian of such
a system is H = −µH X N i=1 σi where σi = ±1
(a) Given that the separation between the spins in the lattice
is larger than their de Broglie wavelength, should the spins be
treated as distinguishable or indistinguishable particles?
