Antimatter interactions?

[YT2095]

I`v had an idea but 1`st I`d like to know a few things before I formulate any further.

it involves Anti-matter, and I`d like to have a few Simple answers.

 

do Antimatter particles Only react with an identical counter particle IE/ Positron meets Electron?

or will it interact with ANY matter? IE/ Anti-proton meets an electron or neutron, or Positron meets a proton or neutron?

[swansont]

It'll only annihilate with the partner. It will have "normal" interactions with everything else — a proton and positron will electrostatically repel each other, and an antiproton and positron will attract and can form antihydrogen.

[YT2095]

damn!

 

that was Not the answer I was hoping for at all

 

oh well, there goes That brain-fart

 

ok, maybe it`s not a Complete loss!

 

how far down the Tinyness scale does this work?

 

does it apply to Sub-atomic particles also?

[Royston]

does it apply to Sub-atomic particles also?

 

An antineutron consists of antiquarks, so yes.

Hmmm, you're planning something fancy YT aren't you! Tell us the rest!

[Gilded]

YT and antimatter? Something awesome and perhaps destruction on a planetary scale is bound to ensue.

/me just noticed that the rain outside is going sidewards again

[YT2095]

oh Hush!

[thedarkshade]

No matter what you are thinking of, you are dealing with matter-antimatter annihilation and I see that as RED ALERT. There is quite a lot energy coming out, so watch it! Think of electron + positron = 938MeV released!

[YT2095]

Chill!

 

it`s only and Idea for an experiment so far, and from what Swansont said, it hardly seems even worth looking at, I can`t argue with Facts!

 

HAD the answer have been Different then we might be cookin` with gas, but they`re not, so End of chat really

 

for now anyway....

[Mr Skeptic]

I think the reason antimatter cannot annihilate with particles other than its own pair because of conservation rules. A positron and quark would violate conservation of charge, for example.

[swansont]

And then breathe a sigh of relief when you realize that shade meant proton/antiproton, since an electron/positron annihilation releases 511 keV.

[thedarkshade]

:( Didn't I write that? Ah crap... Looks like lack of sleep except puffy eyes it also produces a chaos in nervous system...

[YT2095]

it`s that Massive amount of energy that I was thinking of exploiting, if an electron and a positron can give that amount of energy, then it seamed reasonable that things even smaller would give discernible and easily detectable energy levels too.

 

making it the Front end of a really sensitive particle detector

 

in particular I was wondering if this could be used to detect Gravitons, as a way to find out for sure if it`s a direct property of Mass OR gravitons are Every where and mass simply "blocks" some of them so that we`re being Pushed down onto earth, a bit like the casimir effect.

 

I was thinking that setting up such a detector on earth, would you get more "Flashes" detected on the side facing Space, or would you get more on the side facing the earth?

 

as I said at the beginning, it was only an idea
