sudhirking said:Hello. Where are the anti-particles in a nuclie?Are they virtual particles or are there pair production for every particle-antiparticle?
Thank you for clearing up any doubt, but as you say in particle accelators generating antiparticles, how does taht happen and why does that happen. Obviously, some'thing' is generating teh creation of antiparticles. Is it due to the magnitude of the collision which undergo electromagnetic interactions that create antiparticles? If so, how?DrChinese said:A lot of questions, maybe this will help a bit.
3. High energy particle colliders (atom smashers) can create anti-matter (as well as matter) which can actually be harnessed for a period of time in the right circumstances.
4. Some nuclear reactions, as well as beta decay of a neutron, generate anti-matter (such as an anti-neutrino - which is a ghostly particle which does not much interact with matter).
I thought in Qm (basics) that phtons are generated due to law of conservation of energy and spin... well then wouldn't photons be virtual particles holding a certain degree of magnitude. If so, how can a photon have an antiparticle as it is chargless and massless, and is that antiparticle created just another phton. And doesn't annhilations give off high energy photons..DrChinese said:A lot of questions, maybe this will help a bit.
2. Virtual particles normally appear in pairs - a particle and a matching anti-particle - which normally annihilate and leave nothing behind in the way of matter or energy. I.e. no net new matter or anti-matter is created this way.

Anti-particles, also known as anti-matter, are located in the nucleus of an atom, just like regular particles. They are present in equal numbers in most stable atoms, but are usually quickly annihilated when they come into contact with regular particles.
Anti-particles can be formed in a nucleus through the process of pair production, where a high-energy photon interacts with an atomic nucleus and creates a particle-antiparticle pair. Alternatively, they can also be created through the decay of other particles in the nucleus.
Yes, there are several different types of anti-particles that can be found in a nucleus, such as anti-electrons (positrons), anti-protons, and anti-neutrons. These anti-particles have the same mass as their regular counterparts, but have opposite charges.
When anti-particles and regular particles come into contact with each other, they undergo a process called annihilation. This results in the conversion of their mass into energy, in the form of high-energy photons. This process is commonly used in particle accelerators to study the properties of anti-particles.
While anti-particles can be created in a nuclear reaction, they are not typically found naturally in a nucleus. This is due to their short lifespan and tendency to quickly annihilate when they come into contact with regular particles. However, scientists have been able to observe and study anti-particles through the use of particle accelerators and other high-energy experiments.
