In turn, a nuclear clock uses the transition to other levels of atomic nuclei, not electrons, to measure time. However, most atomic nuclei have energy levels that are too far apart for a laser to affect them. The exception is the thorium element nucleus, thorium-229.<\/p>\n\n\n\n
The result of the experiment<\/h2>\n\n\n\n
The researchers used a laser to push the thorium-229 nuclei to a higher energy level and observed the light emitted. The experiment made it possible to determine the transition energy: it is 8.35574 electrons\/volts.<\/p>\n\n\n\n
This number is consistent with measurements made in 2023 but is about 800 times more accurate. To create a nuclear clock, scientists will need to improve the accuracy of such measurements, but the first step in this direction has already been taken.<\/p>\n","protected":false},"excerpt":{"rendered":"
Scientists have come close to creating a nuclear clock. It will be simpler, more accurate, and more portable than an atomic chronometer.<\/p>\n","protected":false},"author":9,"featured_media":1016,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[497,553],"tags":[560,17,3],"class_list":["post-1014","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-novyny","category-nauka","tag-yadernyj-godynnyk","tag-doslidzhennya","tag-nauka"],"yoast_head":"\n
