TRANSITION WAVELENGTHS FROM ( 2p2p )³P STATES TO ( ls2p )³ P STATES FOR HELIUM ISOELECTRONIC SEQUENCE UP TO Z = 10

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