The distinction is at the heart of the useful technique in strong-field physics, wherein a quantum process is envisaged as being followed by a classical interaction between, for example, a photoelectron and the field that produced it. Despite the widespread use of this ...

Quantum Numbers, Orbitals, and Probability Patterns
... Solutions to Schrödinger’s equation involve four special numbers called quantum numbers. (Three of the numbers come from Schrödinger’s equation, and the fourth one comes from an extension of the theory.) These four numbers completely describe the energy of an electron. Each electron has exactly four ...

... But Postulate I says u(x) should be continuous. Now, outside 0 < x < a, V(x) ─►∞. This is unphysical, the particle can't be there! So u(x) = 0 at x = 0 and x = a. This is a BOUNDARY CONDITION. u(x = 0) = A • 0 + B • 1 = 0 so B = 0. (required!) u(x = a) = A • sin ka = 0. But now, I can't set A = 0 'c ...

The electron shells proposed by Bohr are still used, but the electrons in each shell are not all equal in energy. The shell has ...
