Nuclei - Result Question 73

74. In the nuclear decay given below:

[2009]

ZAX⟶Z+1AY⟶Z−1A−4B∗⟶Z−1A−4B,

the particles emitted in the sequence are

(a) γ,β,α

(b) β,γ,α

(c) α,β,γ

(d) β,α,γ

Show Answer

Answer:

Correct Answer: 74. (d)

Solution:

  1. (d) ZAX⟶Z+1AY:β,AZ+1Y⟶Z−1A−4B∗:α

Z−1A−4B∗⟶Z−1A−4B:γ(β,α,γ)

Mass number and charge number of a nucleus remains unchanged during γ decay)
