Abstract: 
Radioactive beryllium isotope ions (Be-7(+) and Be-10(+)) that are provided by a projectile fragment separator with approximate to 1 GeV beams, as well as stable isotope ions (Be-9(+)) are stored and laser cooled in an online ion trap. Their absolute transition energies of the 2s S-2(1/2)-> 2p P-2(3/2) transition were measured with an accuracy of similar to 10(-8). In this way isotope shifts of beryllium ions were obtained and the differential mass polarization parameter kappa=-0.286 41(70) a.u. as well as the 2s S-2 -> 2p P-2 transition energy of an infinitely heavy beryllium ion h nu(infinity)=0.145 524 290(42) a.u. were determined for the first time.
