The positron-electron pair coincidence spectrum occurring in the beta decay of 7.4-sec N16 has been examined at 1.25% resolution with an intermediate-image pair spectrometer. A line is observed corresponding to internal pair conversion of the 6.14-Mev E3 transition from the 3-second excited state to the 0+ ground state of O16. The upper limit on the intensity of a 6.06-Mev nuclear pair line from the 0+ first excited state (electric monopole transition) is 10% relative to the 6.14-Mev line and this corresponds to an upper limit of 1.5×10-4 for the fractional beta decay to the 6.06-Mev level. A lower limit of 8.2 is derived for the ft value of this 2- -->0+ beta-ray branch as compared with the known ft=6.7 for the 2- -->0+. 10.4-Mev branch to the ground state.
