Radioactive beryllium isotope ions ({sup 7}Be{sup +} and {sup 10}Be{sup +}) that are provided by a projectile fragment separator with {approx_equal}1 GeV beams, as well as stable isotope ions ({sup 9}Be{sup +}) are stored and laser cooled in an online ion trap. Their absolute transition energies of the 2s {sup 2}S{sub 1/2}{yields}2p {sup 2}P{sub 3/2} transition were measured with an accuracy of {approx}10{sup -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 {sup 2}S{yields}2p {sup 2}P transition energy of an infinitely heavy beryllium ion h{nu}{sup {infinity}}=0.145 524 290(42) a.u. were determined for the first time.
