✦ Synopsis

The fluorescence of Ni atoms isolated in NC. Ar, I(I and Xe matrices has been investigated, including time-resolved measurements. From an analysis of the emission spectra. a matrix shift for the 3ds4s2 3 the gas phase) with respect to rhe 3dg-Is' 3 F4 level (the gound state of Ni in D3 state was deduced to be ~0, 36,10 and 34 meV for Ne, Ar, Kr and Xe, respectively. Because the latter level is only 25 meV above the 3d ' 4s * 3F4 level in the "-_ts phase, this matrix shift constitutes a ground-state change for Ni in Ar, Kr and Xe, and confirms previously reported results.
