Question

In the nuclear transmutation,
${}_4^{9}Be+X{\to }_4^{8}Be+Y$
$(X,Y)$ is/are:

• A. $(\gamma ,n)$
• B. $(p,D)$
• C. $(n,D)$
• D. $(\gamma ,p)$

Answer 1

Answer: (A), (B)

$(p,D)$

The reaction can occur by following two ways,
${}_4^{9}Be+\gamma {\to }_4^{8}Be{+}_0^{1}n$
${}_4^{9}Be{+}_1^{1}H{\to }_1^{2}H{+}_4^{8}Be$
