Há 16 horas · Special Feature. Sensing a Nuclear Kick on a Speck of Dust. July 8, 2024 • Physics 17, 108. Scientists have detected the decay of radioactive nuclei by tracking the recoil of dust-sized spheres on which the nuclei were embedded.

Há 16 horas · Nuclear Decay Detected in the Recoil of a Levitating Bead. Tracy Northup. Department of Experimental Physics, University of Innsbruck, Innsbruck, Austria. July 8, 2024 • Physics 17, 107. A levitating microparticle is observed to recoil when a nucleus embedded in the particle decays—opening the door to future searches of invisible decay ...
Há 16 horas · When atomic nuclei and subatomic particles interact, the results are incredibly complex. These are the "many body problems" of quantum mechanics. To help make sense of these interactions ...
Há 5 dias · The historical detection of gravitational waves from a binary neutron star merger has opened the new era of multimessenger astronomy and has propelled neutron stars to the center of a variety of disciplines, such as astrophysics, general relativity, nuclear physics, and particle physics.
Há 5 dias · Naturally occurring uranium contains only about 0.7 percent U-235. Most of the remainder is the isotope U-238. To be used in a nuclear power plant, uranium must be enriched to contain more U-235 ...
