(a) Verify the l = 0 and l = 1 Numerov-method H-atom energies given in Section 6.9 for 270 points and for 1080 points, with rr going from 10-15 to 27. You must uncheck the Make Unconstrained Variables Non-Negative box in the Solver Parameters box in Excel 2010.
(b) For 1080 points and rr going to 27, the n = 3, l = 0 Numerov Er of - 0.05510 is still substantially in error. Use the Numerov method to improve this energy significantly without decreasing sr.
