... Here ϕ1 and ϕ2 are spin wave functions of the first and the second nucleus respectively. U is the wave function of the center of mass motion. V is the wave function of the relative motion. Spin of the nucleus is zero, S = 0. Hence ϕ1 = ϕ2 = 1. V (~r1 − ~r2 ) = χ(| r~1 − r~2 |)Ylm (~ r1 − r~2 ) where ...

Bell's theorem

Bell's theorem is a ‘no-go theorem’ that draws an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. This theorem is named after John Stewart Bell.In its simplest form, Bell's theorem states:Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from ""indifference"" to ""wild extravagance"". Lawrence Berkeley particle physicist Henry Stapp declared: ""Bell's theorem is the most profound discovery of science.""Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables). Bell concluded:Bell summarized one of the least popular ways to address the theorem, superdeterminism, in a 1985 BBC Radio interview:
