摘要：

A detailed level collisional-radiative model of the E1 transition spectrum of Ca-like W34+ ion has been constructed. All the necessary atomic data has been calculated by relativistic configuration interaction (RCI) method with the implementation of Flexible Atomic Code (FAC). The results are in reasonable agreement with the available experimental and previous theoretical data. The synthetic spectrum has explained the EBIT spectrum in 29.5-32.5 angstrom, while several new strong transitions has been predicted to be observed in 18.5-19.6 angstrom for the future EBIT experiment with electron density n(e) = 10(12) cm(-3) and electron beam energy E-e = 18.2 keV.
