    In electron cyclotron resonance of metals/solids can there be electron acceleration without them engaging in collision ? I read the last para of electron cyclotron resonance wikipedia page which stated this

    You shouldn't say something like this in this forum without providing a directly link.

    It isn’t saying the electrons never collide. It is saying that the cyclotron frequency is higher than the collision rate so electrons can accomplish complete orbits between collisions.

    As @Cutter Ketch has stated, it doesn't mean that there are no collisions. It means that the mean free path of the electrons is larger than the length it takes to make one complete orbit.

    This clearly illustrates why we require exact citation of the sources. We don't know if you are reading a bad article, or if you're misreading and misinterpreting a correct article.
