In the nuclear decay given below AZX → AZ+1Y → A-4Z-1B* → A-4Z-1B, the particles emitted in the sequence are (a) γ, β, α (b) β, γ, α (c) α, β, γ (d) β, α, γ

Answer: (d). X → Y: A same, Z up by 1, so β⁻. Y → B*: A down by 4, Z down by 2, so α. B* → B: excited nucleus to ground state, no change in A or Z, so γ. So the answer is (d) β, α, γ.

Radioactive Decays: Alpha, Beta, Gamma

In the nuclear decay given below

${}^{A}_{Z}X \rightarrow {}^{A}_{Z+1}Y \rightarrow {}^{A-4}_{Z-1}B^{*} \rightarrow {}^{A-4}_{Z-1}B,$

the particles emitted in the sequence are

Show answer and solution

Answer: (d)

$X \to Y$ : $A$ same, $Z$ up by 1, so $\beta^-$ .
$Y \to B^*$ : $A$ down by 4, $Z$ down by 2, so $\alpha$ .
$B^* \to B$ : excited nucleus to ground state, no change in $A$ or $Z$ , so $\gamma$ .
So the answer is (d) $\beta, \alpha, \gamma$ .
