gaurav314 Posted July 28, 2012 Share Posted July 28, 2012 what exactly happens during a neutron-neutron,proton-neutron and neutron proton collision?? Link to comment Share on other sites More sharing options...
Iota Posted July 28, 2012 Share Posted July 28, 2012 Nuclear fission or fusion, maybe nothing. Depends. Here's the little amount I know about nuclear fusion: When two protons fuse together energy is released. According to Einstein's E=mc2, mass is lost in the form of energy; two non-fused protons have more mass than two that are fused together. Link to comment Share on other sites More sharing options...
mathematic Posted July 28, 2012 Share Posted July 28, 2012 Most collisions will be scattering. It takes a lot of energy (like in the interior of the sun or in the LHC) to produce more complicated reactions. Link to comment Share on other sites More sharing options...
alpha2cen Posted July 30, 2012 Share Posted July 30, 2012 (edited) what exactly happens during a neutron-neutron,proton-neutron and neutron proton collision?? Without electrostatic force barrier(++ or - - ), particles could be easily fused by nuclear force. Edited July 30, 2012 by alpha2cen Link to comment Share on other sites More sharing options...
Enthalpy Posted August 11, 2012 Share Posted August 11, 2012 Fission with two nucleons, that would be new. Fusion between two neutrons has never been seen and this still needs an explanation. Between two protons, it never produces a di-proton (whose mass is hence unknown), which also remains to be explained. Mass is energy whatever the form of energy: it can be speed, chemical energy, height, heat... In a dam, water loses mass which is converted into electricity in the turbine and the alternator. In fusion, the strong force releases energy available for instance in a neutron's speed, while in fission, electrostatic repulsion releases energy available in the fragments' speed. Because nuclear energy is more concentrated, the mass variation is more perceptible and such figures get practically usable. That's all about mass variation. In a collision at higher energy like at the LHC, nearly anything can happen (mainly particles production), and the result depends much on the collision energy and very little on what the initial particles were.

If particles get over the electrostatic barrier, the particles are easily fused by nuclear force. And then, they will go decaying or maintaining their structure depending on their energy state in the nucleus . Two proton binding state is very unstable, so it can easily decay into other particle composition. Link to comment Share on other sites More sharing options...

Why do you feel the need to give some sort of explanation, just as if Nature had to obey to your understanding? The absence of a di-neutron is still an open question within the existing theories. Same for the di-neutron. Link to comment Share on other sites More sharing options...

Fe is the most stable atom. http://en.wikipedia...._binding_energy But I have not found the equation about the nuclear stability yet. A paper tried to solve this problem by using electron charge stability in the nuclear. http://www.scienceforums.net/topic/68124-how-charge-is-distributed-in-nucleon-nucleus/page__view__findpost__p__694690 Neutron stability give us some doubt about the origin of the atom. http://www.scienceforums.net/topic/67290-dark-matter-and-dark-energy/page__view__findpost__p__696163 Edited August 11, 2012 by alpha2cen Link to comment Share on other sites More sharing options...
Enthalpy Posted August 12, 2012 Share Posted August 12, 2012 You should make a very clear mental difference between science and pseudo-science as in some links you give. Link to comment Share on other sites More sharing options...
alpha2cen Posted August 12, 2012 Share Posted August 12, 2012 Stability chart is correct. The remainders are in progress. Link to comment Share on other sites More sharing options...
JohnStu Posted September 18, 2012 Share Posted September 18, 2012 what exactly happens during a neutron-neutron,proton-neutron and neutron proton collision?? nothing spectacular. The high energy enough collisions in the lab do create fascinating stuff though. Daily, protons hit other protons in interstellar space Link to comment Share on other sites More sharing options...
