  2. Prompt neutron - Wikipedia

    en.wikipedia.org/wiki/Prompt_neutron

    In nuclear engineering, a prompt neutron is a neutron immediately emitted (neutron emission) by a nuclear fission event, as opposed to a delayed neutron decay which can occur within the same context, emitted after beta decay of one of the fission products anytime from a few milliseconds to a few minutes later.

  3. Prompt criticality - Wikipedia

    en.wikipedia.org/wiki/Prompt_criticality

    In nuclear engineering, prompt criticality describes a nuclear fission event in which criticality (the threshold for an exponentially growing nuclear fission chain reaction) is achieved with prompt neutrons alone and does not rely on delayed neutrons. As a result, prompt supercriticality causes a much more rapid growth in the rate of energy ...

  4. Neutron stars in fiction - Wikipedia

    en.wikipedia.org/wiki/Neutron_stars_in_fiction

    Since they were first hypothesised, neutron stars have formed part of the milieu of science fiction. [ The Encyclopedia of Science Fiction ] describes the terminology as "much used in SF". Indeed neutron stars and pulsars often seem to appear as part of the background setting of science fiction stories.

    en.wikipedia.org/wiki/ROBLOX

    Roblox occasionally hosts real-life and virtual events. They have in the past hosted events such as BloxCon, which was a convention for ordinary players on the platform. [46] Roblox operates annual Easter egg hunts [52] and also hosts an annual event called the "Bloxy Awards", an awards ceremony that also functions as a fundraiser. The 2020 ...

  7. Inhour equation - Wikipedia

    en.wikipedia.org/wiki/Inhour_equation

    The prompt neutron lifetime in a modern thermal reactor is about 10 −4 seconds, thus it is not feasible to control reactor behavior with prompt neutrons alone. Reactor time behavior can be characterized by weighing the prompt and delayed neutron yield fractions to obtain the average neutron lifetime, Λ=l/k, or the mean generation time ...

  8. Delayed neutron - Wikipedia

    en.wikipedia.org/wiki/Delayed_neutron

    In nuclear engineering, a delayed neutron is a neutron emitted after a nuclear fission event, by one of the fission products (or actually, a fission product daughter after beta decay), any time from a few milliseconds to a few minutes after the fission event. Neutrons born within 10 −14 seconds of the fission are termed "prompt neutrons".

  9. Crossover (fiction) - Wikipedia

    en.wikipedia.org/wiki/Crossover_(fiction)

    Fan fiction fusions between different science fiction movies and series are often created, such as Star Wars and Star Trek or Babylon 5 and Stargate. M.U.G.E.N. is a fighting game engine that features many fan-created and fictional characters and stages from various television series, movies, as well as other video games.
