摘 要：Detailed theoretical calculations are performed for the 4f and 5p inner-shell excitations of W-W^(3+) ions using the multiconfiguration Hartree–Fock method in order to better understand the origin of the XUV photoabsorption spectra of W atoms from the dual laser-produced plasma experiment(Costello et ***.B 24(1991)5063 and the spectra of photon-induced single ionization of W^(q+) ions(q=1,2,3)(Müller et ***.T1441(2011)014052)from photon-ions merged beam experiments,*** broad and strong resonances in the experimental spectra have also been theoretically identified mainly from 5p–5d *** 4f–5d,6d and 5p–6d transitions also make a small contribution to each spectrum,which are superimposed on the 5p–5d transition *** on the assumption of a normalized Boltzmann distribution among the excited states,we succeed in reproducing spectra which are in good agreement with experiments.
