Parity of the 5.83-MeV State ofN14

The lifetime of the $J=3\mathrm{}$ 5.83-MeV level of ${\mathrm{N}}^{14}$ has been examined with pulsed-beam and coincidence techniques. The 5.83-MeV state was populated by means of the ${\mathrm{C}}^{12}({\mathrm{He}}^3, p){\mathrm{N}}^{14}$ reaction. The mean life obtained for the 0.73, 5.83→5.10-MeV transition is ≤0.3 nsec. This limit for the mean life, together with the polarization measurement of Rose et al., establishes the relative parity of the 5.83- and 5.10-MeV levels to be the same. Since the 5.10-MeV level has been established as 2- by Warburton et al., the parity of the 5.83-MeV level is -.
