... values of A : 0, 1, and (b) We interpret this as asking for the number of distinct values for mA (this ignores the multiplicity of any particular value) For each A there are A + possible values of. .. 2 2 Thus, the multiple of h / 8mL2 is 44 2 2 2 20 Using Eq 3 9-2 0 we find that the lowest four levels of the rectangular corral (with this specific “aspect ratio”) are non-degenerate, with energies... lowest possible energy of the system is Eground = 17.25(h2/8mL2) Thus, the multiple of h / 8mL2 is 17.25 21 (a) Promoting one of the electrons (described in problem 19) to a not-fully occupied higher
