Abstract

A parity nonconservation asymmetry was observed in the reaction ${}^{19}F$ ( $\vec{p}, α_{0}$ ${}^{16}O$ . Longitudinally polarized protons with an energy of 670 keV hit a S $F_{6}$ gas target. The resonant proton capture leads to the 13.482-MeV, $1^{+}$ , $T = 1$ state in ${}^{20}{Ne}$ . The analyzing power for this reaction was determined for six proton energies around 670 keV. The maximum of the analyzing power $A_{max} = (6.6 \pm 2.4) \times 10^{- 3}$ was deduced from a bestfit interference curve to these points.
