-
Scientists almost create a nuclear clock-a precise clock that uses a low energy transition in the core of the Torio-229 atom to keep time.
-
Electric interferences make atomic watches unsuitable for detecting dark materials, but nuclear clocks do not have this problem and can give the resolution about 100,000 times better than what we currently have.
-
There is no guarantee that using a nuclear clock you will finally find theoretical outrage caused by dark material, but this will help scientists to explore a new atomic area as part of that endless search.
It is once considered an unused US Nuclear Program “Torium-229” by-product-sidabrine white metal, torio, isotope-to be the most important search for humanity dark material.
So far scientists have Massive detectors are inventedinterviewed the gravitational effect and examined the cosmic radiation in the hope that it could show evidence of this rude material. Researchers are now considering whether a nuclear clock driven by low energy transitions in the TRIO-229 nucleus can act as a new method in particle hunting.
To A new study Published in the magazine Physical review xScientists from Germany, Israel and Spain have studied ways to determine the influence of the dark material of the unique nuclear clock. Today, the most accurate watches (atomic watches) depend on the electron vibrations between two quantum states to keep time. Although these watches are very accurate, they are sensitive to electrical interference. For proposed nuclear watches using atomic nuclei, these disorders are significantly less affected.
The frequency of the resonance-the nucleus between the “Earth” and “high energy”-is usually quite large, so strong radiation requires stinging the nucleus and producing the nuclear clock “The forehead” of the mite. However, Toris-229 is special because its resonance frequency is low enough to excite it with modern laser technology, theoretically making a nuclear clock.
“When it comes to Dark Mater, the Torio-229-based nuclear clock would be the main detector,” Gilad Perez said in a press release, a co-author of the Weizmann Institute of Science. […]; We appreciate [nuclear clocks] will allow us to detect 10 trillion times weaker forces than gravity, providing a resolution 100,000 times better than what we currently have in search of dark material. ‘
In recent years, laboratories around the world have made a great breakthrough in the development of the Torium-229 nuclear clock, which culminated in a document published in 2024. September In the magazine Nature; This document noted the tracking of the Torio-229 transition, which was more accurate in millions of times than previous attempts.
“In the universe created only in visible material, the physical conditions and absorption spectrum of any substance will remain constant,” said Perez’s press release. “But since the dark materials surround us, a wave -like nature can subtly change the mass of atomic kernels and cause temporary shifts of their absorption spectrum […]; We still need even more accuracy to create a nuclear clock, but we have already found the possibility of exploring the dark material. ‘
There is no guarantee that nuclear clocks will end in our Dark Mater hunting, but they reflect a new atomic wall, which must yet be explored as part of that endless search.
Not so bad for isotope, once considered to be the simplest “by -product”.
