prati-kan

parishoonyan
Diagram illustrating the particles and antiparticles of electron, neutron and proton, as well as their "size" (not to scale). It is easier to identify them by looking at the total mass of both the antiparticle and particle. On the left, from top to bottom, is shown an electron (small red dot), a proton (big blue dot), and a neutron (big dot, black in the middle, gradually fading to white near the edges). On the right, from top to bottom, are show the antielectron (small blue dot), antiproton (big red dot) and antineutron (big dot, white in the middle, fading to black near the edges).
kan (baayein) aur prati-kan (daayein) ke aakaar aur vidyut aavesh ka chitran. oopar se neeche ilektraun/pojeetraun,protaun/pratiproton, nyootraun/pratinyootraun.

kisi bhi kan se sambaddh pratikn bhi hota hai jiska dravyamaan abhinn hota hai lekin vidyut aavesh vipreet hota hai. udaaharan ke liye ilektraun ka prati-kan prati-ilektraun ek dhanaaveshit kan jise pojeetraun kehte hain, saamaanyat: ise rediyodharmi padaarthon ke kshaya se banaaya jaata hai.

prakruti ke niyam kanon aur pratikno ke liye lagbhag samamiteeya hote hain. udaaharan ke liye ek pratiproton aur pojeetraun se prati-haaidrojan parmaanu ka nirmaan hota hai, jiske gunadharm bhi haaidrojan parmaanu ke samaan hi hain.

kan-pratikn vilopan

Feynman diagram of a kaon oscillation. A straight red line suddenly turns purple, showing a kaon changing into an antikaon. A medallion is show zooming in on the region where the line changes color. The medallion shows that the line is not straight, but rather that at the place the kaon changes into an antikaon, the red line breaks into two curved lines, corresponding the production of virtual pions, which rejoin into the violet line, corresponding to the annihilation of the virtual pions.

yadi ek kan aur prati-kan yathochit kvaantam avastha mein hain to vo donon ek doosare ko vilupt karke koi anya kan ka nirmaan kar sakte hain. abhikriya e- + e+ → γ + γ (ilektraun-pojeetraun ka do fotono mein vilopan) ek udaaharan hai. mukt aakaash mein e- + e+ → γ (ilektraun-pojeetraun ka ekal foton mein vilopan) sambhav naheen hai kyonki is abhikriya mein oorja va sanveg sanrakshan donon ek saath sambhav naheen hain. yadyapi naabhik ke kulaam kshetr mein yeh sambhav hai.
