Xenon - Wikipedia
WEBXenon has atomic number 54; that is, its nucleus contains 54 protons. At standard temperature and pressure, pure xenon gas has a density of 5.894 kg/m 3, about 4.5 times the density of the Earth's atmosphere at sea level, 1.217 kg/m 3. [50]

Limits on the luminance of dark matter from xenon recoil data
WEBMay 17, 2023 · Here we report a direct search for effective electromagnetic interactions between dark matter and xenon nuclei that produce a recoil of the latter from the PandaX-4T xenon-based detector...
How Dark Matter Physicists Score Deals on Liquid Xenon
WEBJan 11, 2018 · The detectors sense flashes of light that should appear when a dark matter particle bumps into a xenon nucleus. They’ve chosen to use xenon because it’s not reactive, which means less noise in...
Dark Matter Detector Observes Rarest Event Ever Recorded
WEBJun 14, 2022 · The evidence for xenon decay was produced as a proton inside the nucleus of a xenon atom converted into a neutron. In most elements subject to decay, that happens when one electron is pulled...

WEBAug 30, 2024 · Xenon, chemical element, a heavy and extremely rare gas of Group 18 (noble gases) of the periodic table. It was the first noble gas found to form true chemical compounds. More than 4.5 times heavier than air, xenon is …
An Absorbing Dark Matter Experiment - Physics
WEBOct 13, 2022 · The PandaX team searched this data for evidence of a beyond-the-standard-model interaction in which a fermionic dark matter particle is absorbed by the nucleus of a xenon atom. After the absorption, the xenon nucleus should recoil while emitting either a neutrino or an antineutrino.
Xenon - Periodic Table and Atomic Properties - Material Properties
WEBAtomic Number – Protons, Electrons and Neutrons in Xenon. Xenon is a chemical element with atomic number 54 which means there are 54 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.

WEBMar 1, 2021 · We report on a search for nuclear recoil signals from solar B 8 neutrinos elastically scattering off xenon nuclei in XENON1T data, lowering the energy threshold from 2.6 to 1.6 keV. We develop a variety of novel techniques to limit the resulting increase in backgrounds near the threshold.
Dark-matter detector observes exotic nuclear decay - Nature
WEBApr 24, 2019 · The xenon-124 nucleus captures two electrons from the surrounding electron shells, which results in the conversion of two protons (circled) into neutrons, and the emission of two neutrinos.
