Why the spin part of wavefuncition of two particle of half-integer spin (fermions)(adsbygoogle = window.adsbygoogle || []).push({});

which was created after desintegraton of spinless particle is always

antisymmetric (let's assume that orbital angular momentum was 0

before and after desintegration). This implies that spatial part

of wavefunction is symmetric (maybe it the result of momentum

conservation???).
