Inducing fission with a slow neutron

Inducing fission with a slow neutron

Schematic of uranium-235 absorbing a thermal neutron, forming unstable uranium-236, then splitting into barium-144, krypton-89, and three fast neutrons with a small chain reaction sketch Induced fission is when a heavy nucleus is made to split by absorbing a neutron. For uranium-235, a slow neutron is absorbed to form unstable 92236U{}^{236}_{92}\text{U}92236​U, which then breaks into two smaller nuclei, several neutrons, and energy.

Step-by-step lessons on AQA A Level Physics Induced fission (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
