Okay kiddo, let me explain to you what radiative auger effect is!
Imagine you have a little toy boat on a lake. The boat is like an atom and the lake is like the space around it. Inside the boat, there are little toys that represent the electrons. They move around and can jump from one toy boat to another toy boat if they want to.
Now, sometimes when an electron is jumping from one boat to another, it can give off some energy in the form of light. This is like when you have a flashlight and you turn it on - the light comes out of the flashlight and travels through the air.
But sometimes, instead of giving off the energy as light, the electron can give it to another electron inside the same boat. When that happens, both electrons get some extra energy and they start moving faster.
This is called the Auger effect. But there's another way this can happen too!
When an electron gives its energy to another electron inside the same atom, sometimes that energy can make the electron jump from the innermost shell to the outermost shell. This is like one of the toys in the boat jumping from the bottom to the top!
When that happens, the atom gives off some energy as light. This is called the radiative Auger effect. It's like if the boat suddenly lit up and became brighter.
So basically, the radiative Auger effect is when an electron in an atom gives some energy to another electron inside the same atom, and that makes the electron jump to a higher shell and give off some light.
