[time-nuts] New atomic clock

[Michael Costolo]

I guess my point was the neutron is a nuclear particle and so the concept of it's orbit seemed, out of place. Hence my confusion.  Excitation of neutron energy states might have been more appropriate language?  Now where is my copy of Eisberg and Resnick?
