What is another word for avoided crossing?
Pronunciation: [ɐvˈɔ͡ɪdɪd kɹˈɒsɪŋ] (IPA) 
Avoided crossing is a phenomenon observed in quantum mechanics where two energy levels come close to each other but do not actually cross. This phenomenon is also known as anticrossing or noncrossing. A synonym for avoided crossing is diabolic point, as it marks a point where two energy levels interact to form an anti-resonance. Other synonyms for avoided crossing include conical intersection, which occurs when two potential energy surfaces intersect at a single point, and avoided level crossing, which is commonly used in nuclear physics. Despite the different terms used to describe the avoided crossing phenomenon, they all refer to the same underlying physical principle of quantum mechanics.
