For a large range of {ital Z} the 1{ital s}2{ital s}{sup 1}{ital S}{sub 0}{minus}1{ital s}2{ital p}{sup 3}{ital P}{sub 1} interval in heliumlike ions lies in a wavelength region accessible by infrared lasers. Measurements of this interval will enable exceptionally sensitive tests of calculations of relativistic corrections and QED effects (Lamb shifts) in two-electron ions. This Letter describes a precision measurement of this interval in N{sup 5+} using a fast ion beam and a CO{sub 2} laser. Our result is compared with recent relativistic and QED calculations. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.
