Abstract: Doubly excited intrashell 2p23Pe states in heliumlike N5+ and O6+ions are calculated by using the original Slater-type wave function and the modified configuration interaction wave function. Using the modified Slater-type wave function having up to 393 and 276 terms for N5+ and O6+,we predicted the energy positions of the discrete 2p23Pe states for these two heliumlike ions. They are -11.140748676 a.u. and -14.726670741 a.u., respectively. Several expectation values of rin and r12m (-1 ≤ n ≤1, and -1 ≤ m ≤ 2) are also given in the present letter. The present results indicate that the modified Slater-type wave function in which r< and r> coordinates are incorporated is effective and powerful for the description of the 2p23Pe state showing strong correlation effect in two-electron systems.
