Using the conservation laws, state which interaction is possible:
|
|
proton + electron => neutron + neutrino (e-)
|
|
|
proton + neutron ==> proton + proton + anti-proton
|
|
|
Either A or B
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Recently, it was found that, in weak interaction, there are three levels of conservation of additive quantum numbers [5]: at the first (the highest) level, Q, B, L and fermion quantum number F are conserved including all kinds of fermions (both quarks and leptons).
Detailed explanation-2: -One of the rules that must be followed in nuclear reactions is the Law of Conservation of Lepton Number.
