i everybody i've studied in my 9th standard that x rays are produced when cathode rays(electrons) hit solid targets such as molybdenum,titanium,etc.. now we'll observe the physics going out there so what's happening there? an electron is coming with some speed say v and hitting the valence electron present in the valence shell or orbit of the molybdenum atom and eventually a x ray is emitted whose speed is c(speed of light) so my doubt here is the electron transition is taking place above there and an x ray is produced so in the large hadron collider if two electrons are made to hit at almost at 99.99% of the speed of light even then will an x ray is produced? if so,what are the other particles that emit when they(electrons) collide? thanks!!!
