Question

In order to examine the interior structure of the proton and the neutron, experiments at the stanford linear accelerator center (SLAC) used a beam of electrons of energy 20 GeV as a probe. What is the de broglie wavelength of such electrons? What is the size of the smallest structural detail that can be resolved by such electrons? (momentum must be calculated from the relativistic formula for momentum (c^2)p^2 = E^2 - (m^2)c^4)

Answer 1

de broglie wavelength = x= 2 now, E- prer+ mock now the rest mass energy of electron is moc²=0.511 may where E= 20 Gev. pre = (20000) ² (0.511)2 = (20000) mer² = (20000 (1.602x103) prer = 100265616x 10 11 12 P=10068x1017 " = 6.204x1017 m=0.062 from 1.068 x 1017 - the smallest structural detail that can be resolved is d-goal a. 6.626610-34
