Thus the reaction is       possible, through the strong interaction . ( h ) For the reaction K +  + n    Σ +  + p 0  +  γ , the conservation laws are Charge:     + 1 + 0 = + 1 + 0 + 0; Spin: 0 +  !  = –  !  + 0 + 1; Baryon number: 0 + 1 = + 1 + 0 + 0; Lepton number: 0 + 0 = 0 + 0 + 0. Strangeness: + 1 + 0 ? – 1 + 0 + 0. Thus the reaction is       forbidden, strangeness is not conserved . ( i ) For the reaction K +    p 0  + p 0  + p + , the conservation laws are Charge:     + 1 = 0 + 0 + 1; Spin: 0 = 0 + 0 + 0; Baryon number: 0 = 0 + 0 + 0; Lepton number: 0 = 0 + 0 + 0; Strangeness: + 1 = 0 + 0 + 0. Thus the reaction is       possible, through the weak interaction . ( j ) For the reaction p +    e +  +  ν e   , the conservation laws are Charge:     + 1 = + 1 + 0; Spin: 0 =  !  –  ! ; Baryon number:
