From the case of \(\beta^{+}\) decay, the colliding photon is,
where a time axis swap results in the expected \(g^{+}\) particle.
And in the case of \(\beta^{-}\) decay, the colliding photon is,
where \(t_T\leftrightarrow t_c\) from a \(P_{p^{+}}\) particle. This is a \(P_{T^{-}}\) photon or a magnetic-gravito wave. The radioactive decay is then,
where a time axis swap produces the \(p^{+}\) particle as expected.
Which are the actual photon pair involved in \(\beta\) decay?
