4.1. Using the nearly free-electron approximation for a one-dimensional (1-D) crystal lattice and assuming that the only nonvanishing Fourier coefficients of the crystal potential are v(n/a) and v(-π/a) in (4.73), show that near the band edge at k = 0, the dependence of electron energy on the wave vector k is given by where m* = Ek electron at k = 0. = Eo + = mo[1 − (32m²aª / hªлª)v(π/a)²]¯¹ is the effective mass of the ħ²k² 2m*
Ignoring the fine structure splitting, hyperfine structure splitting, etc., such that energy levels depend only on the principal quantum number n, how many distinct states of singly-ionized helium (Z = 2) have energy E= -13.6 eV? Write out all the quantum numbers (n, l, me, ms) describing each distinct state. (Recall that the ground state energy of hydrogen is E₁ = -13.6 eV, and singly-ionized helium may be treated as a hydrogen-like atom.)
