Precision experiments using fast beam laser interaction

摘要: A summary is presented of two different experiments: By exciting fast atomic beams in the energy range from 60 to 150 keV with resonant laser light and by observing decay flight lifetimes Li22P12and Na32P12 are measured be (27.29±0.04) ns (16.40±0.03) ns, respectively. By a laser-induced M1 resonance transition helium-like fluorine beam F=12–32 F=32–52 hyperfine components 1s2p 3P1-3P2 fine-structure interval have been measured. The energies 953.60(3) cm−1 961.77(3) cm−1, respectively, which the-structure splitting Δ12 = 957.88(3) cm− extracted.
