Homework Statement
Indicate the fundamental interactions through which the following processes occur.Justify.
n -> p+ e- + -νe...1
p+p -> p+p+n+-n...2
π+ -> μ++ -νμ...3
γ -> e+ + e-...4
Homework Equations
The Attempt at a Solution
1... is possible due to weak decay .electron antineutrino production.
2... is possible due to baryon no. conservation.
3... is not possible as lepton no. is not conserved.
4...is possible due to pair production and if energy of gamma rays is greater than 1.02MeV.It has been expermentally proven.
Are my deductions correct?? I am a particle, nuclear physics beginner.[/B]
