STUDY NOTES · CHAPTER 1
Independent study material. These notes are an independently authored revision aid based on standard non-
relativistic quantum mechanics (following the treatment in Griffiths & Schroeter, Introduction to Quantum
Mechanics) and on general patterns observed in how this material tends to be assessed. They are not affiliated
with, endorsed by, or sourced from the University of South Africa (UNISA) or any official assessment body, and all
practice problems are original variations written for study purposes, with independently worked solutions. © AMP

PHY3708 Atomic and Nuclear Physics (Unisa). This chapter is the module's compressed tour
through non-relativistic quantum mechanics, before the course turns to nuclei from Chapter 2 onward.
Based on a review of how this material tends to be assessed, the recurring high-yield tasks are: the
harmonic-oscillator dimensionless-variable derivation reducing the Schrödinger equation to the
Hermite equation; constructing a hydrogen-like wave function's radial and angular parts for a named
state and finding its nodes; and applying the kinetic-energy operator to a piecewise-defined 1D wave
function to extract a normalization constant and an expectation value. The abstract vector-space
"Formalism" material is covered only briefly below, as background — it rarely appears directly in
assessment.
