A

`._937)^(81)Rb + ._(-1)^(0)e rarr ._(36)^(81) Kr + ...`

B

`._(6)^(11)C rarr ._(5)^(11)B + ...`

C

`._(7)^(14)N + ._(2)^(4)He rarr ._(8)^(17) O + ...`

D

`._(27)^(60m) Co rarr ._(27)^(60) Co + ...`

Text Solution

Verified by Experts

The correct Answer is:
`(d)`
A radiiocatice element may gives `gamma-` radiations susequently after emssion of `alpha-` or `beta-` decay, the newly formed element has higher energy level. That is why `gamma` emission is secoundary emission. Also `.^(60m)Co` is metastable state formed radioactive decay.
