The electron emission yield from the doubly excited states 2p{sup 2}({sub 1}D) and 2s2p({sup 1}P) in helium were measured at the reduced ion energy of 1.67Mev/u. Carbon ions of charge states 4 to 6 were used as projectiles. The observation angles were between 47.7{degrees} and 132.3{degrees} with respect to the beam direction. The relative electron emission yield for these states were studied as a function of the angle. The total emission yields for each state were obtained as a function of the projectile charge state. These results will be compared to previous results and theoretical calculations.
