Web0(a is the Bohr radius) to make the answerhavedimensions of energy (thus it is now valid in ordinary units). Equation (50) is the final expression for the hyperfine structure energy shift in hydrogen in the case ℓ 6= 0. However, one can show that the same answer holds also in the ca se ℓ = 0, so Eq. (50) applies in all cases. 8. The New ... Web(the fine structure constant) times the Bohr radius: ¯h mc = αa0 = e2 ¯hc ¯h2 me2 = 3.9×10−11cm (electrons).

WebWell, Owen Chamberlain [professor of physics, UC-Berkeley] I think took the lead in organizing it. Again it may have been the FAS that acted as a network to encourage other people.
