Lamb shift in muonic ions of lithium, beryllium and boron

Abstract

We present a precise calculation of the Lamb shift $(2P_{1/2}-2S_{1/2})$ in muonic ions $({\mu }_3^{6}Li{)}^{2+},({\mu }_3^{7}Li{)}^{2+}$, $({\mu }_4^{9}Be{)}^{3+},({\mu }_4^{10}Be{)}^{3+}$, $({\mu }_5^{10}B{)}^{4+},({\mu }_5^{11}B{)}^{4+}$. The contributions of orders ${\alpha }^3÷{\alpha }^6$ to the vacuum polarization, nuclear structure and recoil, relativistic effects are taken into account. Our numerical results are consistent with previous calculations and improve them due to account of new corrections. The obtained results can be used for the comparison with future experimental data, and extraction more accurate values of nuclear charge radii.
