Extraction of the electron mass from <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>g</mml:mi></mml:math>-factor measurements on light hydrogenlike ions

Abstract

The mass of the electron is determined to its 12th digit in a high-precision experiment with ${}^{12}{C}^{5+}$ ions, where the dependent theoretical value of the $g$ factor is accurately calculated by including high-order QED corrections.
