Abstract

The emission of $^{10} Be$ in ternary cold neutronless spontaneous fission of $^{252} Cf$ is observed with the Gammasphere consisting of 72 detectors. The $γ$ ray corresponding to the decay of the first $2^{+}$ state in $^{10} Be$ is observed in coincidence with the $γ$ rays of the fission partners of $^{96} Sr$ and $^{146} Ba$ . The yield to the first excited state of $^{10} Be$ in the $^{96} Sr -^{146} Ba$ split is the order of $4.0 \times 10^{- 4}$ per 100 fission events.
