Determine the relation between the coe²cients a and b and the “direction” of the particle’s spin given by the spherical coordinates θ and φ . 3.)

Comment on the symmetry of these states under the particle exchange operator. 4.) Bertulani Problem 1.6 (Chap. 1, Prob. 6) 5.) Given that J π = 1 + for the deuteron, that the pion has spin zero, and that the reaction π+ d → n + n can be observed when the πis captured at rest, determine the parity of the π....
