Absolute multiplet strengths for dipole transitions between 1s4l 1,3 L and 1s4l′1,3 L′ of the helium isoelectronic sequence have been calculated in the L-S coupling scheme exactly up to first order in perturbation theory within the context of the Z -1 expansion method. Calculated f values for helium transitions are compared with accurate variational results. f values for Li+ transitions are obtained using experimental transition energies.
