POLARIZATION MEASUREMENTS ON THE 5.83 $Yields$ 5.10 Mev GAMMA TRANSITION IN N$sup 1$$sup 4$
An experiment has been made to obtain information about the relative parity of the 5.83 Mev and 5.10 Mev states in N/sup 14/. Using the reaction C/ sup 13/(p, gamma )N/sup 14/ at the 1.47 Mev resonance measurements have been made to determine the transition from the J = 3, 5.83 Mev state to the J = 2, 5.10 Mev state. If the transition is mainly dipole in character, as has been concluded by Warburton, Rose and Hatch from a Doppler shbft measurement on the 0.73 Mev gamma ray, the results of the present measurements give conclusive evidence that it must be M1 (with possible small admixtures of E2) and, hence, that the 5.83 Mev and the 5.10 Mev state have the same parity. In as much as a preference for an odd-parity assignment of the 5.83 Mev state is indicated by previous work, this preference, then, is also given for the 5.10 Mev, J = 2 state. Further polarization measurements on the Ni/sup 60/ 1.17 Mev gamma radiation and the 0.42 Mev radiation following the Coulomb excitation of Ag/sup 107/109/ have been made in order to calibrate the polarimeter.
