The term "forbidden mechanism" can have different meanings depending on the context in which it is used. Here are a few interpretations across different fields: 1. **Physics and Chemistry**: In these disciplines, a "forbidden mechanism" often refers to a reaction pathway or process that is not allowed under the laws of conservation or quantum mechanics. For example, in nuclear physics, certain decay processes may be classified as "forbidden" if they do not obey the selection rules governing allowed transitions.
