Cluster decay, also named heavy particle radioactivity, heavy ion radioactivity or heavy cluster decay, [1] is a rare type of nuclear decay in which an atomic nucleus emits a small "cluster" of neutrons and protons, more than in an alpha particle, but less than a typical binary fission fragment.
Since the Alpha release of 7 Days To Die, there have been multiple major updates containing features such as a new snow biome, forging systems, new weapons, general graphical changes and smoother terrains. Alpha 7.8 was released on April 4, 2014, followed by Alpha 7.9 on April 8, [1] and Alpha 7.10 April 19.
In particle physics and nuclear physics, the branching fraction (or branching ratio) for a decay is the fraction of particles that decay by an individual decay mode or with respect to the total number of particles which decay.
Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), [1] especially for environments in outer space (especially beyond low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear ...
First particle collisions in all four detectors at 450 GeV. 30 Nov 2009 LHC becomes the world's highest-energy particle accelerator achieving 1.18 TeV per beam, beating the Tevatron's previous record of 0.98 TeV per beam held for eight years. [116] 15 Dec 2009 First scientific results, covering 284 collisions in the ALICE detector. [117] 30 Mar ...
Supernova neutrinos are weakly interactive elementary particles produced during a core-collapse supernova explosion. [1] A massive star collapses at the end of its life, emitting on the order of 10 58 neutrinos and antineutrinos in all lepton flavors. [2]
The Mach number (M or Ma), often only Mach, (/ m ɑː k /; German:) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound.
An early Hughes YAH-64 prototype with T-tail. After the AH-56 Cheyenne was cancelled in 1972 in favor of projects like the U.S. Air Force A-10 Thunderbolt II and the Marine Corps AV-8A Harrier, the United States Army sought an aircraft to fill an anti-armor attack role that would still be under Army command.
