Calculate the stopping power of a proton with an energy of 5 MeV in water, using hand calculations. Please show all work. For this question, use the following values for proton constants, which should be accessible, or given in the lecture content. I = 74.6 eV ii. N = 3.38 x 1023 e-/cm3

.Using the P-Star code online, compute the stopping power of a 5 MeV proton in water: https://physics.nist.gov/PhysRefData/Star/Text/PSTAR.html.

Compare the results and any differences in value, give a potential reasoning for different results from hand calculations and calculated results.

Using the P-Star code, compute the range of a 5 MeV proton in water

Considering the considerable difference in mass between an alpha particle and proton, calculate the stopping power of a 5 MeV alpha using Table 1 and hand calculations. Hint: consider the relationship between the particles for certain values.

Using the A-Star code online, compute the stopping power of a 5 MeV alpha in water: https://physics.nist.gov/PhysRefData/Star/Text/ASTAR.html.

Compare the calculated values from sub-questions 5 and 6. 8. Using the A-Star code, compute the range of a 5 MeV alpha particle in water.
