In a high-energy electron scattering experiment on the nucleus, a scientist has scientist has possibilities to use energies of 200, 2000 and 20000 MeV. Which energy should the scientist use? Do the calculations and give the necessary arguments to show why the scientist makes the right decision.

The mass of the atom 9F is 18.99840 amu. Calculate the binding energy per atom. Answer Units: [x10-11 J]

Compute the approximate nuclear radius of: U (ن) (d) Nit -12 I allatiun c Actinium-89

Chlorine is an unusual element in that it has two abundant stable isotopes, Cl-35 and Cl-37, constituting, respec-tively, about 76% and 24% of natural chlorine. The masses of these isotopes in unified atomic mass units are, to three significant figures, equal to their mass numbers 35 and 37. A mass spectrom-eter like that described in Example 26.1 and Fig. 26.7 is used with singly ionized chlorine atoms. The spectrometer has a 3.50-kV accelerating potential and a 163-mT magnetic field. How far apart will Cl-35 and Cl-37 ions be when they reach the detector?
