If the cueball is spinning in the opposite direction (accomplished by hitting the bottom of the white with the cue), apon contact with the object ball, it will stop and then will begin to travel backwards once the (backspin) takes effect.
Now in the case of a stun,for the white to stop completely dead, the cueball must not be rolling in either direction, but simply skidding across the cloth. Set up a straight shot fairly close to the object ball and this is easy. You simply hit slightly below centre at a resonable pace, the cueball will simply skid across the cloth, without spinning at all, and stop once it reaches the object ball. Now extend this distance to a shot over say 9 foot. and play the same pace, the same height on the cueball. The cueball will initially skid across the cloth, but after a certain distance, friction of the cloth will cause it to start spinning forwards. This is effectively a stun run through, as the white will follow a short distance past the object ball and is a very advanced shot.
So in order for the cueball to have no rotational movement upon contact with the object ball, you must hit initially with some backspin, that is to say hitting the bottom of the ball. Friction with the cloth will cause the white to stop spinning backwards, and eventually begin rolling forwards again. The trick is for the white to contact the object ball at the point where the backspin has just worn off, but before the white begin rolling forwards. The height you hit on the white and the pace must be judged for each shot, and knowledge of this can only be attained through practice.
So long and the short of it... After what was probably a confusing and conveluted post... There is no difference between a stun shot and backspin
Sorry for the confusing post... It was less confusing in my head then it got longer and longer.... (Its a lot easier to demonstrate in person with a white ball)
And for future reference if you have a specific question about particular shots they can be posted here
