Louis Slotin: Porovnání verzí

According to Weinberg and Wigner,<ref>Alvin M. Weinberg and Eugene P. Wigner. ''The Physical Theory of Neutron Chain Reactors''. Chicago: University of Chicago Press, 1958. Page 595.</ref> Slotin was the first to propose the name [[dollar (reactivity)|dollar]] for the interval of reactivity between delayed and [[prompt critical]]ity; 0 is the point of self-sustaining chain reaction, a dollar is the point at which slowly released, delayed neutrons are no longer required to support chain reaction, and enters the domain called "prompt (super-)critical". Stable nuclear reactors operate between 0 and a dollar; excursions and nuclear explosives operate above a dollar. The hundredth part of a dollar is called a [[cent (reactivity)]].<ref>Hugh C. Paxton: ''A History of Critical Experiments at Pajarito Site''. Los Alamos Document [http://www.atomictraveler.com/LANLPajarito.pdf LA-9685-H], 1983.</ref> When speaking of purely prompt critical events, some users refer to cents "over critical" as a relative unit.<ref>{{cite book| last=McLaughlin| first=Thomas P.| title=A Review of Criticality Accidents|year=2000| publisher=Los Alamos National Laboratory| location=Los Alamos| url=http://www.orau.org/ptp/Library/accidents/la-13638.pdf| id=LA-13638| accessdate=5 November 2012| page=75|display-authors=etal}}</ref>
