Question

Part A

Calculate the binding energy per nucleon for 235U.

Express your answer to three significant figures and include the appropriate units.

Part B

Calculate the binding energy per nucleon for the fission product 137Cs.

Express your answer to three significant figures and include the appropriate units.

MeV/nucleon unit is not working on mastering physics. What is other unit that is suitable?

When a nucleus of 235U undergoes fission, it breaks into two smaller, more tightly bound fragments.

Explanation / Answer

1)

m_proton + m_netron + m_electron - m_U

= 92*1.007276466812 + 92*5.4857990943e-4 + 143*1.008664916 - (235.0439299)

= 1.9151 u

= 931.494061 * 1.9151 MeV

= 1784 MeV

=1784/235 = 7.59 MeV/nucleon

2)

m_proton + m_netron + m_electron - m_Cs

= 55*1.007276466812 + 55*5.4857990943e-4 + 82*1.008664916 - (136.9070895)

= 1.2338 u

= 931.494061 * 1.2338 MeV

= 1149 MeV

= 1145/137 = 8.388 MeV/nucleon
