摘要: Dramatic reductions of the linewidths well-known deep centers in $^{28}\mathrm{Si}$ reveal ``isotopic fingerprints'' constituents. The $\ensuremath{\sim}1014\text{ }\text{ }\mathrm{meV}$ Cu center, thought to be either a pair or an isolated Cu, is shown contain four atoms, and $\ensuremath{\sim}780\text{ Ag center Ag. $\ensuremath{\sim}944\text{ $^{*}\mathrm{Cu}$ different configuration pair, fact contains three one Ag, new two-Cu two-Ag found. $\ensuremath{\sim}735\text{ previously assigned Fe, actually Au Cu. This suggests family four-atom (Cu, Au) centers.
