Is it possible to slow an electron in such a way(for example using a cyclotron to decelerate the electron ) that it completely stops. And since we created the slowing mechanism we might be able to predict its position when it is in rest. But this is in violation to the uncertainty principle. Can anyone help me with this?Thanks.
Thank you for your answers, they all made me learn something new. As you wanted me to give a clearer explanation of what I had in mind: A cyclotron is used to accelerate particles right. If we use the same mechanism but send an electron in through the original exit of the cyclotron and reverse the direction of B field and apply the electric field in such a way as to decelerate the electrons between the 2 Ds of the cyclotron ,then, after a long time the electron would still be going in circles and its speed would go on decreasing.so if we wait long enough we might be able to violate the uncertainty principle? Am i right?
