- Problem 7.3. Consider a system consisting of a single hydrogen atom/ion, which has two possible states: unoccupied (i.e., no electron present) and occupied (i.e., one electron present, in the ground state). Calculate the ratio of the probabilities of these two states, to obtain the Saha equation, already derived in Section 5.6. Treat the electrons as a monatomic ideal gas, for the purpose of determining J-1) Explain why any physically realizable solution to the Schrodinger’s equation must be square-integrable. 2)The Chebyshev polynomials of the first kind can be otained from the recurrence relation, Tn+1(x) = 2xTn(x) −Tn−1(x) with T0(x) = 1 and T1(x) = x.a) Show that any two Chebyshev polynomials are orthogonal with respect to the weighting factor (1 − x2)− 12 inthe closed interval [−1, 1]. b) Pick the first three Chebyshev polynomials and use Gram-Schmidt orthonormalization procedure to form anorthonormal set in the closed interval [−1, 1].An electron is trapped in a one-dimensional infinite potential well in a state with quantum number n = 17.

Is it a state of definite momentum? Explain.An electron is trapped in a one-dimensional infinite potential well that is 100 pm wide; the electron is in its ground state. What is the probability that you can detect the electron in an interval of width x = 5.0 pm centered at x = (a) 25 pm, (b) 50 pm, and (c) 90 pm? (Hint: The interval x is so narrow that you can take the probability density to be constant within it.)
