What shape do electron probability fields have when they are unbound?
According to quantum mechanics, electrons bound in an atom have probability fields of electrons that look something like this.
I can’t seem to find a similar representation for unbound electrons or partially bound electrons. I was taught in high school physics that the physical speed of electrons through electrical wires was around 1m/s – but what shape are their probability distributions? What about electrons being discharged in a cathode ray tube?
On a slightly different note, do we have similar probability distributions for protons/neutrons in an atomic nucleus?
