Abstract.The even parity mp1/25np′ and mp1/25nf′ autoionizing resonances of Ar, Kr, and Xe (m=3,4,5) were investigated experimentally and theoretically by one-photon
excitation from lower-lying intermediate levels. In particular, high
resolution measurements for the Ar(nf′), Kr(12p′,8f′), and Xe(8p′)
resonances are reported; lineshape parameters for these resonances have been
derived by a Fano-type analysis, thus yielding reduced resonance widths. The
experimental spectra and the resonance parameters are compared with
theoretical calculations which are based on the configuration interaction
Pauli–Fock approach including core polarization. The measured and
calculated lineshapes are in good agreement. In addition, theoretical predictions are presented
for other resonances, which have not yet been observed experimentally, and some
systematic trends are elucidated.
