Аннотация:
Three different calculational methods (AUTOLSJ, MZ, MCDF) were used to obtain energy levels and autoionization rates for doubly excited states 2l3l' of two-electron systems (10<or=Z<or=42). When all the transpositions of the levels are done according to the Wigner-von Neuman theorem (noncrossing of the levels with the same total angular momentum J and parity of the system along the Z isoelectronic sequence), it becomes possible to compare energy levels and autoionization rates obtained by the three methods. The Z dependences of the quantities are investigated for each calculational method for 10<or=Z<or=42. The final comparison reveals rather good agreement between the results obtained by the three methods.
