Problem Set 5


NOTE: You may have to look at the Nuclear Table or the Element Tables to answer some of the questions.

1) Write the equation for a neutron being transferred from 7Li to 16O.
ANSWER
EXPLANATION

2) Looking at the Nuclear Table, can you see any reason why a neutron is more likely to be transferred from 7Li to 16O than from 16O to 7Li?
ANSWER

3) Write the equation for a neutron being transferred from 2H to 42Ca
ANSWER
EXPLANATION

4) Suppose a beam of 2H nuclei collides with a target of 3H. Scientists observe alpha particles (4He) emerging from the collision volume. What other particle is produced in this process? Write the equation.
ANSWER
EXPLANATION

5) Write the equation for neutron absorption on plutonium-239.
ANSWER
EXPLANATION

6) A proton strikes a nucleus of 2H. Three particles emerge from the collision. What are they? Describe what has happened in words.
ANSWER

7) In the reaction, 73Li + 147N --> X + 178O, what is X?
ANSWER
EXPLANATION

8) A proton transfer reaction is less likely than a neutron transfer reaction, but it could happen. For example, suppose a proton is transferred from carbon-12 to neon-21. The reaction would be

126C + 2110Ne --> 115B + X.

What is X? Make sure you understand why boron-11 is produced.
ANSWER
EXPLANATION

9) What are the products in a proton transfer from zirconium-92 to lead-208?
ANSWER
EXPLANATION

10) The nuclei, 3He and 2H collide. One product of the reaction is an alpha particle. What else is produced?
ANSWER
EXPLANATION

11) Write the equation for neutron absorption on lithium-6.
