In Equations ( ), (10), and (11), N is equal to the the number of exchangeable particles in the system before the MC move , V is the volume of the system, Λ corresponds to the thermal de Brogli wavelength of the exchanged particle, β equals the Boltzmann factor (β = 1/k B T ), and E 1 and E 2 are the potential energy values of the system before and after the MC move.
