WebApr 8, 2024 · The total number of states having energy between zero and E is Ntotal = 4πR2 = 4πE(2mL2 ℏ2π2) So, the density of states between E and E + dE is Ω(E) = dNtotal dE = 4π(2mL2 ℏ2π2) That is, in this 2-dimensional case, the number of states per unit energy is constant for high E values (where the analysis above applies best).
