摘要: Improved measurements of isotope shifts in the 4s2 1S0-4s5s 1S0 transition calcium are reported for stable isotopes. A comparison with shift other transitions by means a King plot shows satisfactory agreement. Values changes mean-square nuclear charge radius delta (r2) from combined analysis muonic and electron scattering data used to separate mass field optical lines. This procedure leads values isotopes 40Ca 48Ca using all available high-precision data. The results (r2)A,40 3.2(2.5), 215.3 (4.9), 125.4 (3.2), 283.2 (6.4), 118.8 (5.9), 124.2 (5.0), 5 (13) -4.4(6.0)*10-3 fm2 A=41 48 respectively. electronic factors relating observed deduced, discussed terms configuration mixing calcium.
