As the lightest fundamental massive particle, the electron is one of nature’s few central building blocks. A precise knowledge of its intrinsic properties, such as its mass, is mandatory for the most accurate tests in physics - the Quantum Electrodynamics tests that describe one of the four established fundamental interactions in the universe. The underlying measurement principle combines a high-precision measurement of the Larmor-to-cyclotron frequency ratio on a single hydrogen-like carbon ion studied in a Penning trap with very accurate calculations of the so-called bound-electron g-factor. For the isotope-shift measurement, the bound-electron g-factors of two lithium-like calcium isotopes have been measured with relative uncertainties of a few 10^{-10}, constituting an as yet unrivaled level of precision for lithium-like ions. \u003cbr\u003e\n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783319845111\"\u003e\u003ch3\u003eHigh-Precision Measurements of Bound-Electron g-Factors of Highly Charged Ions\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783319508764\"\u003e\u003ch3\u003eHigh-Precision Measurements of Bound-Electron g-Factors of Highly Charged Ions\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783319845111","offer_id":39426592899165,"sku":"9783319845111","price":106.99,"currency_code":"EUR","in_stock":true},{"title":"Hardcover - 9783319508764","offer_id":51681155974,"sku":"9783319508764","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/7fcbcf96-90f3-4c0f-a920-232b761de6dd.jpg?v=1775794872","url":"https:\/\/shop.autorenwelt.de\/products\/the-electron-mass-and-calcium-isotope-shifts-von-florian-kohler-langes","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
