A search was made for an electron-positron pair transition from the 10.98-Mev 0- state of 0/sup 16/to the 0/sup +/ ground state using the F/sup 19/ (p, alpha )O/sup 16*/ reaction and an intermediate-image pAir spectromoeter. No 10.98-Mev pairs were observed with an intensity as great as 2 x 10 /sup -5/ that of the 3.86 Mev M1 cascade gamma ray from the 10.98Mev to the 7.12-Mev 1-state. This result suggests a lower limit of UPSILON > 2 x 10-/sup 8/ sec for the partial lifetime of a 10.98-Mev 0->0/sup +/ pair transition. (auth)
