What is the weak atomic force?
Weak interaction
{'answer_start': array([-1]), 'answer_text': array([''], dtype=object)}
In any given interaction, weak isospin is conserved: the sum of the weak isospin numbers of the particles entering the interaction equals the sum of the weak isospin numbers of the particles exiting that interaction. For example, a (left-handed) π+
, with a weak isospin of 1 normally decays into a ν
μ (+​1⁄2) and a μ+
 (as a right-handed antiparticle, +​1⁄2).[16]
