Abstract

It is shown that the recent observation of the parity-forbidden

α

decay,

{}^{16}O

(8.87 MeV) →

{}^{12}C

{}^{4}{He}

, requires that the weak parity-violating (nucleon → nucleon+vector-meson) amplitudes be nonzero and thus demands the presence of noncanceling seagull and Schwinger terms in these amplitudes.
