Measurement of the <i>g_J</i> factor of a bound electron in hydrogen-like oxygen ¹⁶O⁷⁺

Abstract

The magnetic moment of the electron bound in hydrogen-like oxygen O 7+ has been determined using the "continuous Stern–Gerlach effect" in a double Penning trap. We obtained a relative precision of 2 x 10 –9 . This tests calculations of bound-state quantum electrodynamics and nuclear correction. PACS No.: 32.10Dk
