Alpha decay is by far the most common form of cluster decay, where the parent atom ejects a defined daughter collection of nucleons, leaving another defined product behind. It is the most common form because of the combined extremely high nuclear binding energy and relatively small mass of the alpha particle.
Gamow solved a model potential for the nucleus and derived from first principles a relationship between the half-life of the alpha-decay event process and the energy of the emission, which had been previously discovered empirically and was known as the Geiger–Nuttall law. [11]
Apocalyptic fiction is a subgenre of science fiction that is concerned with the end of civilization due to a potentially existential catastrophe such as nuclear warfare, pandemic, extraterrestrial attack, impact event, cybernetic revolt, technological singularity, dysgenics, supernatural phenomena, divine judgment, climate change, resource depletion or some other general disaster.
Children of Time is a 2015 science fiction novel by author Adrian Tchaikovsky. The novel follows the evolution of a civilization of genetically modified Portia labiata (arachnoid) on a terraformed exoplanet , guided by an artificial intelligence based on the personality of one of the human terraformers of the planet.
In the center of the island, there may be competition between alpha decay and spontaneous fission, though the exact ratio is model-dependent. [2] The alpha decay half-lives of 1700 nuclei with 100 ≤ Z ≤ 130 have been calculated in a quantum tunneling model with both experimental and theoretical alpha decay Q-values, and are in agreement ...
On TikTok, parents are sharing viral stories and videos of their Gen Alpha kids — those born in 2010 or later — channeling the honey badger as they stand up to injustices and take a no-holds ...
Children born from 2010 to 2024 are part of "Generation Alpha," the demographic successor to Gen Z. They are already being called "feral," illiterate" and "doomed," with bad parenting by ...
