Direct observation of the double Auger decay of a {ital K} hole
- Department of Physics, Tennessee Technological University, Cookeville, Tennessee 38505 (United States)
The double Auger (DA) decay of a {ital K} hole has been observed directly by detecting the two emitted electrons in coincidence. The hole was created in {sup 37}Cl following the electron-capture decay of {sup 37}Ar. The probability of DA decay, per Auger decay, with the two electrons both having an energy greater than 250 eV was found to be 3.7{plus_minus}0.2{percent}. The DA probability was found to decrease exponentially as the energy partitioning between the two electrons changed from the asymmetric case ({ital E}{sub 1}{gt}{ital E}{sub 2}) to the symmetric case ({ital E}{sub 1}{approx_equal}{ital E}{sub 2}). The DA probability accounts for the bulk of the intensity of high charge states previously measured in {sup 37}Cl. {copyright} {ital 1996 The American Physical Society.}
