英文摘要:
Strong configuration interactions are observed in Be-like ions between 1s(1)2s(2)nl(1) and 1s(1)2p(2)nl(1). Such configuration interactions not only make a remarkable and systematic difference to the k-shell transition from 1s(1)2p(2)nl(1) to 1s(2)2p(1)nl(1), but they also change the order of the spectral positions between the transitions 1s(1)2p(2)nl(1) - 1s(2)2p(1)nl(1) and 1s(1)2s(1)2p(1)nl(1) - 1s(2)2s(1)nl(1). Including or not including the configuration interaction of 1s(1)2s(2)nl(1) can result in an energy difference of about 6 eV for the 1s(1)2p(2)nl(1) - 1s(2)2p(1)nl(1) transitions of Be-like aluminum. This phenomenon reveals the physical reason behind the existence of differences between the experimental transmission and the theoretical transmission for aluminum plasma in the paper by Zhang et al (2009 Phys. Rev. E 79 016401). For two configurations (KLMf)-L-i-M-j... and (KLMf'')-L-i'-M-j'..., the strongest configuration interactions may appear when the number of electrons in each shell is the same and the parity for each shell is the same.
