State-selective cross sections [sigma][sup +[sup *]](nl) have been measured for ionization-excitation of helium in collisions with fully stripped ions. The energies of the H[sup +], Li[sup 3+], B[sup 5+], and C[sup 6+] were .83 MeV/u and 1.60 MeV/u. These relate to collision velocities of 5.8 and 8.0 a.u. Data for the Lyman series, He[sup +](np[r arrow]1s), have been measured by observation of the extreme ultra-violet spectra in the 22 to 31 nm wavelength range. The 2p- 1s data is presented and analyzed in terms of a simple power law dependence on the projectile charge state, Z[sub p][sup n]. For the two equivelocity series of cross sections the powers, n, derived from least squares fits to the data were 2.89[plus minus]0.3 and 2.83[plus minus]0.4.
