Laser spectroscopy of Be-7,10(+) in an online ion trap Academic Article uri icon

abstract

  • Radioactive beryllium isotope ions (Be+7 and Be+10) that are provided by a projectile fragment separator with 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 1/2 2 2p P 3/2 2 transition were measured with an accuracy of 10-8. In this way isotope shifts of beryllium ions were obtained and the differential mass polarization parameter =-0.28641 (70) a.u. as well as the 2s S2 2p P2 transition energy of an infinitely heavy beryllium ion h =0.145524290 (42) a.u. were determined for the first time. 2006 The American Physical Society.
