Coherent Production as a Means of Determining the Spin and Parity of Bosons

Analysis of coherent nuclear reactions to determine the parity and spin of a product boson is discussed. The case of production of a vector or axial particle by an incident pseudoscalar pi or K, with its subsequent decay into two spin zero particles, is treated as an example. Decay angular distributions from bosons of spin 1, 2, 3 into bosons of spin zero and unity are listed. (D.C.W.)
