Transition wavelengths from (2p2p)3P states to (1s2p)3P states for helium isoelectronic sequence up to Z=10

Abstract

The wavelengths have been calculated for the (2p2p)3P-(1s2p)3P transition for helium-like ions ranging from z=2 to 10. The energy values of both (2p2p)3P and (1s2p)3P states include relativistic correction and mass-polarisation. Radiative corrections are added to the energy values of the (1s2p)3P. Our results agree with experiments.
