Hi, just wondering whether the commutation relation [\phi,L_3]=i\hbar holds and similar uncertainty relation such as involving X and Px can be derived ?
thanks
for beta decay
n --> p + e- + antineutrino
since neutron has quarks udd while proton has uud, only the d changes to u. is it correct to guess that it is the down quark inside the neutron which "transform" into up quark?
ie d --> u + e- + antineutrino
