Consider a binary magnetic system formed by 5 spins ( ) arranged in a row. The spins are interacting only between themselves, each spin with it’s two (or one - for spin 1 and 5) nearest neighbor. The interaction energy between two nearest neighbor spin i and k is: U(i,k)=-?i?k. . Let U be the total energy of the system. Determine the g(U) multiplicity function for this system. (Write up the possible values for U, and correspond g values)
