We studied doubly excited triplet P-c resonances of heliumlike ions, Z = 3-10, below N = 3 threshold. There are ten resonances for each heliumlike ion. These states are classified with quantum numbers, K, T and A. They are five members in the (3)(1, 1)(n)(+)(3 less than or equal to n less than or equal to 7) series, which can also be classified as 3pnp series, and five members in the (3)(-1, 1)(n)(+)(3 less than or equal to n less than or equal to 7) series, classified also as 3dnd series. The energies and widths are compared with other theoretical results. he only experimental results have been obtained by double-electron capture by N5+ using He, H-2 and Ar as targets. Our results are in good agreement with other theoretical and experimental results. (C) 2003 Elsevier Science B.V. All rights reserved.
