Talk:Neutron temperature

message: Did this replace the article on slow neutrons or something, because I'm getting a lot of pointers to other articles that take me here.theanphibian 16:17, 30 March 2007 (UTC)
thread_title:  [[Incipit]] 

message: "A thermal neutron is a free neutron with a kinetic energy of about 0.025 eV (approx. 4.0×10−21 J; 2.4 MJ/kg, hence a speed of 2.2 km/s) which is the energy corresponding to most probable velocity at a temperature of 290 K (17°C or 62°F), the mode[which?] of the Maxwell–Boltzmann distribution for this temperature."
: Why is "mode" above marked as a 'weasel word'? The Maxwell-Boltzmann distribution has exactly one maximum (= peak = mode of the distribution). Or did I miss something?  —Preceding unsigned comment added by 92.201.96.39 (talk) 14:29, 6 December 2010 (UTC)
replies: text: The 0.025ev, or (1/40)eV is kT at about room temperature.  As far as I know, there is no intent to use mode, but just to ignore small factors like 3/2. One should probably use mean, but that means more unneeded small constants. Gah4 (talk) 18:03, 29 May 2017 (UTC)
thread_title:  Why "which?" 

message: "Moderated and other, non-thermal neutron energy distributions or ranges are listed below:
Fast neutrons have kinetic energies greater than 1 eV, 0.1 MeV or approximately 1 MeV, depending on the definition."
Is the number 0.1 Mev incorrect?  — Preceding unsigned comment added by Zedshort (talk • contribs) 15:41, 31 March 2012 (UTC)
replies: text: I don't know.  This article now says 1 MeV.  — Arthur Rubin  (talk) 14:48, 8 November 2012 (UTC)

message: Why remove the layman's explanation?  The article has a 'this is too technical' tag, so why remove an effort to explain things in plain terms, and put back the too technical tag?  How is that useful?  — Preceding unsigned comment added by 76.100.248.41 (talk • contribs) 01:30, December 18, 2012‎
:Because the "explanation" is your creation (see WP:OR), and is simply wrong.  — Arthur Rubin  (talk) 13:30, 18 December 2012 (UTC)
replies: text: I don't see what can be done to improve a bad explanation. Temperature is related to mean kinetic energy of particles, not vibrations or speed (neutrons always go faster than normal matter of the same temperature).  It is a technical scientific concept about which you don't know the first thing (namely that it IS a scientific concept). So why should we let you explain temperature to laymen? Surely they'll welcome you at the temperature article for that? Okay I admit sarcasm there. See that article's TALK page before splashing in. SBHarris 20:30, 18 December 2012 (UTC)

text: How about you notice that only one other person has made more? . Then check neutron. Then read this talk page from the top to get some idea of the level of discussion. Be bold all you like, but your edits won't last unless they are also correct. SBHarris 02:02, 31 December 2012 (UTC)

message: Okay, I've found/made a good picture (Well, i think it's good, but I'm no graphics dood) of a cold neutron source.
But when I try to upload it, I get nothing.
I swear, it's not random porn.  How the hell do I put up a simple picture?  Why the hell is this so hard to use?
Clue-in appreciated! :)

message: I don't know if it goes here or not, but the stability of reactors comes from the sensitivity to neutron temperature, such that high temperatures reduce the fission rate.  Well, even more, a reactor has to be stable all throughout, not just on average.  Mean-free-path isn't quite long enough to equilibrate though a large reactor. But otherwise, power reactors aren't anywhere close to 290K. Gah4 (talk) 16:06, 13 June 2021 (UTC)
