MIT 22.01: Introduction To Nuclear Engineering And Ionizing Radiation

Lecture 3: Nuclear Mass and Stability, Nuclear Reactions and Notation, Introduction to Cross Section (2016x3)

Date de diffusion: Sept 13, 2016

Today we formally introduce the concept that mass is energy, by exploring trends in nuclear stability. We introduce the notation we’ll use to describe nuclei and their reactions throughout the rest of the course, and introduce nuclear binding energy, analogous to chemical binding energy. We also introduce cross sections, or per-particle nuclear reaction probabilities, showing how a simple, first-order differential equation can result in their definition.
