Answer to Question #227217 in Atomic and Nuclear Physics for BENSON

Question

1. Describe two possible mechanisms by which ¹¹𝑁𝑎₂₂ could decay to ¹¹𝑁𝑒₂₂

2. (a) Write a shorthand nuclear reaction equation of the following equation;

₂𝐻_𝑒⁴ + ₇𝑁¹₄ → ⁸𝑁¹₇ + ₁𝐻¹

(b) Consider the following nuclear reaction equation; ₅𝐵¹₀ + ₂𝐻_𝑒⁴ → ₆𝐶¹₃ + ₁𝐻¹
