The elastic backscattering of low energy electrons from surfaces is strong.

High energy electrons capable of ionizing the material can perform this task.

Higher energy electrons have a greater average radius.

The higher energy electrons overcome the sheath potential and are absorbed.

Getting a high energy electron to collide with an electron would be difficult to make happen.

X-rays are created when high energy electrons hit a metal source.

The betatron was the first important machine for producing high energy electrons.

The attachment of a low energy electron can give rise to two possible reactions for the compound, as shown below.

In order to get high energy electrons, one must illuminate the metal with high-frequency light.

They do involve high energy electrons but the bonds themselves are quite easy to break.
