Modern Physics 5 Question 25

28. From the following equations pick out the possible nuclear fusion reactions

(a) ${ } _6 C^{13}+{ } _1 H^{1} \rightarrow{ } _6 C^{14}+4.3 MeV$

(1984, 3M)

(b) ${ } _6 C^{12}+{ } _1 H^{1} \rightarrow{ } _7 N^{13}+2 MeV$

(c) ${ } _7 N^{14}+{ } _1 H^{1} \rightarrow{ } _8 O^{15}+7.3 MeV$

(d) ${ } _{92} U^{235}+{ } _0 n^{1} \rightarrow{ } _{54} Xe^{140}+36 Sr^{94}+{ } _0 n^{1}$

$+{ } _0 n^{1}+Y+200 MeV$
