The isotope shifts of the 2s~2 ~1So to 2s2 p ~1P_1 and ~3P_1 transitions in the four-electron beryllium atom are calculated by using the multi-configuration Dirac-Hartree-Fock method and the relativistic configuration interaction approach for the stable and short-lived beryllium isotopes.The results provided herein can be employed for the consistency check with the nuclear rms charge radii from the experimental isotope shifts by using the corresponding transitions for the short-lived nuclei ~(7,10-12)Be and ~(14)Be.The analogous isotope shift results could also be obtained for the beryllium-like ions by the methods used here.

The isotope shifts of the 2s ~ 2 ~ 1So to 2s2 p ~ 1P_1 and ~ 3P_1 transitions in the four-electron beryllium atoms are using by the multi-configuration Dirac-Hartree-Fock method and the relativistic configuration interaction approach for the stable and short-lived beryllium isotopes. The results provided here can be employed for the consistency check with the nuclear rms charge radii from the experimental isotope shifts by using the corresponding transitions for the short-lived nuclei ~ (7,10-12) Be and ~ (14) Be.The analogous isotope shift results could also be obtained for the beryllium-like ions by the methods used here.
