摘要: By using a supersonic beam of metastable Ne* atoms and single-mode dye laser we determine the 2p53s–3p specific mass shift 20,22Ne isotopes by means optical spectroscopy. The resulting value, on basis systematic measurement transition isotope shifts at different energies between 15,300 17,000 cm−1, is 473 ± 2.5 MHz. This ~ 50 MHz larger than best-known theoretical value.
