Physicists announce the world's most accurate measure of the lifetime of a neutron

world's most accurate measure of neutron lifetime.

The team's findings, which include scientists from more than 10 national laboratories and universities in the United States and abroad, show improvements twice as much as the previous measurements-with less than one-tenth of uncertainty.

The work is recorded in the journal Physical Review Letters of 13 October. This was the subject of live news at the 2021 Fall Meeting of the American Physical Society Division of Nuclear Physics. A pre-printed version of the paper is also available.

David Baxter, president of the department at IU Bloomington College of Arts and Sciences, said, "This work sets a new gold-standard for measurement that is of fundamental importance to questions such as the relative abundance of elements created in the early universe." Physics. "We are proud of IU's long-term role as a leading institution in this work."

At the time of the study, IU-affiliated authors Nathan Callahan, Maria David and Francisco Gonzalez were graduate students; Engineer Walt Fox; Rudy Chen-Yu Liu, professor of physics; Research scientist Daniel Salvat; And mechanical technician John Vanderwarp. (Callahan and Gonzalez are currently affiliated with the Argonne National…
