NUCLEAR RESONANCE FLUORESCENCE IN Ni$sup 6$$sup 0$

The gamma radiation emitted by a gaseous source of ${\mathrm{Co}}^{60}$${\mathrm{Cl}}_{2}$ has been used to excite the 1.33-Mev level in ${\mathrm{Ni}}^{60}$. The angular distribution of the resonance radiation characterizes the spin of the 1.33-Mev excited state as 2 and the spin of the ${\mathrm{Ni}}^{60}$ ground state as 0.A resonance fluorescence self-absorption experiment has been performed and from it a mean life of (1.1\ifmmode\pm\else\textpm\fi{}0.2)\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}12}$ second has been calculated for the 1.33-Mev excited state of ${\mathrm{Ni}}^{60}$.
