WebJul 12, 2024 · Scientists recently pinpointed how much energy a thorium-229 nucleus needs to make the jump. This is a crucial step toward building a thorium nuclear clock. Thirolf and his colleagues estimated the energy by measuring electrons that the nucleus emitted when it jumped between levels. The team described its findings in Nature two years ago. WebSep 5, 2024 · From atomic to nuclear clocks. 5 September 2024. Peter Thirolf, Benedict Seiferle and Lars von der Wense describe how recent progress in understanding thorium’s nuclear structure, and new upcoming results, could enable an ultra-accurate nuclear clock with applications in fundamental physics.

WebAug 17, 2012 · It has been proposed that a nuclear clock based on a single trapped 229 Th 3+ ion might reach a fractional inaccuracy of 10 −19 [ 17 ]. In the second approach, a macroscopic number (up to 10 18) of thorium atoms is implanted into a VUV-transparent crystal and interrogated simultaneously. WebMar 10, 2024 · The EU-funded ThoriumNuclearClock project will pioneer the development of the first nuclear clock, based on an energy transition in the nucleus of the thorium isotope Thorium-229. This promises to exceed the precision of today’s best atomic clocks (which make use of changes in the energy levels of atomic shell electrons) by up to an order of …
WebApr 15, 2024 · While hints to a potential application of the thorium isomer in the field of frequency metrology can be found already in the early literature on 229m Th, it was in the pioneering publication by Peik and Tamm in 2003 that for the first time a viable concept was presented for building a 'nuclear clock' based on the thorium isomer 229m Th.
WebFeb 27, 2024 · To set a nuclear clock ticking, it needs a nudge with a laser set to exactly the right energy level. But for most nuclei, the energy frequency required is nowhere near accessible with current ...
WebApr 15, 2012 · The 7.8 eV nuclear isomer transition in 229 Thorium has been suggested as an etalon transition in a new type of optical frequency standard. Here we discuss the construction of a "solid-state nuclear clock" from Thorium nuclei implanted into single crystals transparent in the vacuum ultraviolet range. We investigate crystal-induced line … black plated stainless steel earringWebThe Thorium nuclear clock project aims to implement a new type of clock – a nuclear clock. In contrast to electron shell levels used in atomic clocks, it uses quantum states within the atomic nucleus of Thorium-229 as a “ticking” reference. As the nucleus is a thousand times smaller than the electron shell, it reacts much less to ...
