STRENGTHS OF HIGH-ENERGY CAPTURE GAMMA RAYS IN W$sup 18$$sup 4$
S>A possible method for spin measurement is based on capture gamma rays emitted from individual levels. The most direct use of capture gamma rays for the determination of J applies when the ground-state transition is allowed for only one of the spins. An example is the compound nucleus W/sup 184/ in which the electric dipole ground-state transition at 7.42 Mev is allowed for J = 1 but forbidden for J = 0. No information exists concerning the relative transition probabilities involved. Earlier capture gamma measurements with the Brookhaven fast chopper showed strong ground-state transitions for several known resonances of W/sup 184/, indicating that J = I for these resonances. Transition probabilities of the ground-state gamma rays for the five J = 1 levels are tabulated. (A. C.)
