Abstract

The relativistic recoil effect has been the object of experimental investigations using highly charged ions at the Heidelberg electron beam ion trap. Its scaling with the nuclear charge Z boosts its contribution to a measurable level in the magnetic-dipole (M1) transitions of B- and Be-like Ar ions. The isotope shifts of ³⁶Ar versus ⁴⁰Ar have been detected with sub-ppm accuracy, and the recoil effect contribution was extracted from the 1s²2s²2p ²P_1/2-²P_3/2 transition in Ar¹³⁺ and the 1s²2s2p ³P₁-³P₂ transition in Ar¹⁴⁺. The experimental isotope shifts of 0.00123(6) nm (Ar¹³⁺) and 0.00120(10) nm (Ar¹⁴⁺) are in agreement with our present predictions of 0.00123(5) nm (Ar¹³⁺) and 0.00122(5) nm (Ar¹⁴⁺) based on the total relativistic recoil operator, confirming that a thorough understanding of correlated relativistic electron dynamics is necessary even in a region of intermediate nuclear charges.
