A beam of electrons with energy 250 MeV is elastically scattered through an angle of 10° by a heavy nucleus that is at rest. It is found that the differential cross-section is 65% of that expected for scattering from a point-nucleus. Estimate the root mean square radius of the nucleus. Neglect the recoil of the nucleus and use the rest mass of the electron as 0.511 MeV/c2.

Consider a beam of electrons in a vacuum, passing through a very narrow slit of width 2.00?m. The electrons then head toward an array of detectors a distance 1.080m away. These detectors indicate a diffraction pattern, with a broad maximum of electron intensity (i.e., the number of electrons received in a certain area over a certain period of time) with minima of electron intensity on either side, spaced 0.508cm from the center of the pattern. What is the wavelength ?...

1. Beam electrons undergo elastic and inelastic scattering during penetration through a specimen. Elastic scattering generates backscattered electrons that are used in topographic and compositional imaging of the sample.
