I triggered on the very first sentence of this blog. Whereas electrons and neutrinos are elementary particles, the other particle species you mentioned (protons, neutrons, mesons, and so on) are composite objects made of quarks and gluons. Therefore, you may need to fix this sentence that is incorrect.
In addition, note that you have a sentence in French in the middle of the blog, which you may have forgotten to translate:
La forme la plus simple de restitution d'énergie se produit lorsqu'un atome ou une molécule émet le quantum de lumière absorbé dans l'espace, le ramenant à son état initial:
Now, I stop being grumpy ( :p ) and I have a real question. In many of the equations you wrote, like in A* +A == 2A or A*+ B == A+ B, I have the impression that something is missing on the right-hand side. Shouldn’t we have photons and/or energy there? Do you mind clarifying? Thanks in advance!
Cheers!
Hi Mr @lemouth Thank you very much for the correction, for your advices and your valuable additions.
It has been corrected, i was too quick to write trying to finish early because of fatigue (So even the sentence in French I didn't pay attention to it).
As for your question about adding a photon to the equation, this is collisional desactivation of the excited state; which means there is a transfer of energy by collision, from the excited-state molecule A* , to the ground- state molecule B, so A* returns to the ground state without emitting photons (Non- Radiatively).
For example:
Ground state ozone becomes an excited state molecule by absorbing a radiation of 330nm or below, the extra energy is transferred to the nitrogen molecules in the event of collisions with them. The N2 molecules have a higher kinetic energy and move more quickly, which makes the temperature of the atmosphere in that area rises.
Cheers!
Thanks for the answer. In my opinion, this explanation should be added to the main text of the blog, as they way it is currently written is quite confusing. Readers may wonder what is going on as the equations apparently violate energy conservation (a golden rule that cannot be violated in any situation).
Cheers!
I agree with you, I'll make sure it doesn't happen again next time
Thank you
Don't worry if it happens again, I will be there to remind it to you ;)
Lol thank you.
hahahaha it was to force us to practice our french!
As French is my mother tongue, it was OK for me ;)
