Webpurpose of the electron lenses is to create a small, focused electron probe on the specimen. Most SEMs can generate an electron beam at the specimen surface with spot size less than 10 nm in diameter while still carrying sufficient current to form acceptable image. Typically the electron beam is defined by probe diameter (d) in the range of 1 nm WebStrategy. If we assume that the proton confined in the nucleus can be modeled as a quantum particle in a box, all we need to do is to use Equation 7.41 to find its energies E 1 and E 2. The mass of a proton is m = 1.76 × 10 −27 kg. The emitted photon carries away the energy difference Δ E = E 2 − E 1.
