Abstract
Very weak laser resonances of unfavored transitions (n,l)-->(n+1,l-l) have been observed in metastable <(p)over bar(4)>He+ atoms by using a pulsed antiproton beam. The observed wavelengths (713.578+/-0.006 nm f or l=34 and 726.095+/-0.004 nm for l=35), as well as those of the know n favoured transitions, are to a few ppm accounted for by a recent var iational calculation of Korobov [Phys. Rev. A 54, R1749 (1996); and (u npublished)] which includes the relativistic correction to the motion of the electron.
