Concept explainers
(a)
The reason why the reaction is called the pickup reaction.
(a)
Explanation of Solution
The reaction is,
When a nucleon from target nucleus by the incident nucleus, it is called pick-up reaction.
Here, He-3 picks up a nucleon from C-12 and produces He-4.
Conclusion:
Therefore, the reaction is called the pickup reaction as the neutron from the carbon nucleus is picked up.
(b)
The resulting nucleus, X.
(b)
Answer to Problem 13P
Explanation of Solution
Given:
The reaction is
Calculation:
The right side of the reaction has 8 protons and 15 nucleons. The product has 2 protons and 4 nucleons.
Thus, X should have 6 protons and 11 neutrons.
Conclusion:
Therefore, the value of the X is
(c)
The Q value of the reaction.
Whether the reaction is endothermic or exothermic reaction.
(c)
Answer to Problem 13P
Explanation of Solution
Given:
Formula Used:
If the reaction is:
Calculation:
The Q factor is calculated as,
The value is positive which means that this is an exothermic reaction.
Conclusion:
Therefore, the Q value is
