Cosmogenic radionuclides reveal an extreme solar particle
2022年1月11日 · Cosmogenic radionuclides, such as 14 C, 36 Cl, and 10 Be, are produced within the Earth’s atmosphere – mainly in the stratosphere - as a result of the interactions of galactic cosmic rays...
Terrestrial in situ cosmogenic nuclides: theory and application
2001年8月1日 · This article presents the theory necessary for interpreting cosmogenic nuclide data, reviews estimates of parameters, describes strategies and practical considerations in field applications, and assesses sources of error in interpreting cosmogenic nuclide measurements.
Cosmogenic radionuclide production modeling with Geant4: …
2019年5月1日 · Measurements of gamma-ray emissions from the decay of cosmogenic radionuclides provide an opportunity to characterize the elemental composition of a terrestrial planet or asteroid surface. We report on the development of a Geant4 application which models cosmogenic radionuclide production on metal-rich surfaces.
NNDC | National Nuclear Data Center
ENSDF contains recommended nuclear structure and decay data for all the known nuclides, which are obtained following a critical review of all available experimental data, supplemented with systematic trend studies and theoretical models.
Cosmogenic nuclide techniques | Nature Reviews Methods Primers
2022年3月10日 · Cosmogenic nuclides are produced when surface rocks are exposed to the open sky and bombarded by cosmic rays. Primary cosmic radiation, mostly protons born in supernovae in space, hit the...
Cosmogenic Nuclides | Oxford Research Encyclopedia of Planetary …
Therefore, cosmogenic nuclides are a major tool to study the history of small objects in space and of matter near the surfaces of larger parent bodies. A classical application is to measure “exposure ages” of meteorites, that is, the time they spent as a small body in interplanetary space.
List of nuclides - Wikipedia
For a graphical depiction, see table of nuclides. This list of nuclides shows observed nuclides that either are stable or, if radioactive, have half-lives longer than one hour. This represents isotopes of the first 105 elements, except for elements 87 (francium), 102 …
Design and evaluation of prototype readout electronics for nuclide ...
China plans to develop the next generation dark matter particle explorer satellite, referred to as the Very Large Area Space Telescope (VLAST). As an essential step in this process, the prototype design of detectors and electronics for the VLAST is currently underway. The nuclide detector is a core detector in the VLAST.
A new radionuclide identification method for low-count energy …
2022年7月1日 · A new nuclide identification method for low-count energy spectra with multiple radionuclides is developed. The method combines a feature enhancer based on the prior energy information and a neural network to classify the nuclides.
Geochronology and Thermochronology - Wiley Online Library
2017年11月24日 · Applications of cosmogenic nuclides can be broken down into three main classes. Extraterrestrial cosmogenic nuclides are measured in meteorites and on lunar and planetary surfaces. Meteoric cosmogenic nuclides are produced in Earth's atmosphere and track production rates, atmospheric transport, and depositional processes.
