Proton magnetic radius

The Zemach correction is essentially a nontrivial weighted integral of the product of electric and magnetic densities, normalized to unity. It cannot be measured directly, like the rms proton charge radius which determines the main proton size correction to the Lamb shift (compare the case of the proton size correction to the Lamb shift of order Za) in (6.13) which depends on the third Zemach moment). This means that the correction in (11.4) may only conditionally be called the proton size contribution. 

For an accelerator with a radius equal to that of Earth, and a magnetic field of 40 kG, calculate the maximum energy of the protons that could be accelerated.

For determination of the energy of a particles and for identification of a-emitting radionuclides, a. spectrometers are usually applied, having been calibrated by use of a emitters of known energy. Relatively exact determination of the energy of a particles, protons and deuterons can be made by means of a magnetic spectrometer. The relation between the velocity r of the particles, the magnetic flux density B and the radius r of the particles is...
