Inherent lifetime widths of Ar 2p-1, Kr 3d-1, Xe 3d-1, and Xe 4d-1 states -: art. no. 012502

The natural widths of the Ar 2p(-1), Kr 3d(-1), Xe 3d(-1), and Xe 4d(-1) states have been determined from photoelectron spectra measured with very high resolution. Lifetime widths Gamma (L) of 104+/-3 meV and 111 +/-3 meV were obtained for the Xe 4d(3/2)(-1) and 4d(5/2)(-1) states, respectively. In contrast, no differences in the inherent lifetime width could be found for the spin-orbit split components of Ar 2p (Gamma (L)=118+/-4 meV) and Kr 3d (Gamma (L) = 88+/-4 meV) ionized states. The lifetime widths of the Xe 3d(3/2)(-1) and 3d(5/2)(-1) states were found to be 490+/-30 meV and 510+/-30 meV, respectively. The extracted lifetime widths are compared with the previously published experimental results.
