Question

6. In the following list the numbers represent the spin and parity J" for three particles A, B, C. We consider a decay of particle A in the initial state to particles B plus C in the final state. Indicate, for each case, what the value of the orbital angular momentum quantum number, £, should be to allow for conservation of angular momentum (if more tha e indicate two possibilities at east). Indicate whether te reaction is allowed if parity is conserved and whether this imposes restrictions on E.

Answer 1

3p @e(12. ,י-)--GY-c.):(M..e) TT C Hext) Let us lake H,S SD aィ。 TIA) -- rNouw, Va uc

咪ー. since C-ANC u-t RHs as So , reaclion s not alooed USC So,

3 ere (1,0,-1) possible values: Nouo LH.s NNDU IT

So Yeaetion is concoveo TH -1ニ@ OY 13 I

TIA = 3 TTL =-1 Now for TT3x So So 3 for RH

So -1 So)
