# 20320 Quantum Mechanics and Atomic Structure 1

**Credits**: 4 advanced credits in Physics

**Prerequisites**: Differential and Integral Calculus I (or Infinitesimal Calculus I), Differential and Integral Calculus II (or Infinitesimal Calculus II + Infinitesimal Calculus III), Linear Algebra I (or Linear Algebra for Natural Science Students), Modern Physics and Mechanics. Students must also fulfill all **English** requirements and take **bibliographic instruction** in the Library.

Recommended: Quantum Theory I, Linear Algebra II, Introduction to Ordinary Differential Equations

**Authors**: Joseph Dotan, Yoram Kirsh, Yosef Verbin, Aharon Kapitulnik, Jacob Shaham

**Objectives**: To acquaint students with the principles of quantum mechanics; To demonstrate how these principles are reflected in the characteristics of simple quantum systems; To teach students to apply the principles to the solution of physics problems.

**Topics**: The Schroedinger equation; The uncertainty principle; The harmonic oscillator; Matrix mechanics and measurement in quantum theory; Piecewise-constant potentials; Angular momentum – commutation relations and eigenvalues; Angular momentum – matrix elements and eigenstates; The hydrogen and hydrogen-like atoms.

The Open University offers three courses in quantum theory: **Quantum Theory I** (20522), **Quantum Theory II: Chemical Bond** (20523), and this course, **Quantum Mechanics and Atomic Structure**. **Quantum Theory I** is designed as the first course in quantum theory for Physics and Chemistry students and accordingly requires only basic prior knowledge. It begins with a presentation of the principles of quantum theory alongside a review of the required basic background material. Students are therefore advised to take **Quantum Theory I** before enrolling in this course. The current course reviews and expands on several of the topics and discusses more advanced topics as well. **Quantum Theory II: Chemical Bond** is a continuation of **Quantum Theory I** in a different direction, focusing on the principles of molecular structure and on chemical bonding theory.
