Isotopic shift of the ground state of neon from the experimental results concerning the absorption of 0.63-μm laser radiation

Resumo

Isotopic shifts of the 3s[3/2]₁⁰–2р⁶(¹S₀) and 3s'–2р⁶(¹S₀) transitions, equal, respectively, to 417 ± 20 and–98 ± 20 MHz, have been measured using the 0.63-μm radiation of a helium–neon laser and opto-magnetic resonances induced by the interference of the reactive components of fields in overlapping areas of the emissions of isotopic atoms. Combining these results with the absolute specific mass shift of the 3p[5/2]₂ level (–647 MHz), the isotopic mass shift of the ground state of neon equal to 3223 ± 30 MHz, and its specific mass shift equal to–9782 ± 30 MHz have been determined.
