Question

In the nuclear decay given below
`._Z^A X rarr ._(Z-1).^A Y rarr ._(Z-1)^(A - 4) B^** rarr ._(Z-1)^(A-1) B`,
the particle emitted in the sequence are
A. `alpha , beta , gamma `
B. `beta , alpha , gamma `
C. `gamma , beta , alpha `
D. `beta , gamma , alpha `

Answer 1

Correct Answer - B
`""_(Z)X^(A) overset(beta)to ""_(Z+1)Y^(A) overset(alpha)to ""_(Z-1)B^(A-4) overset(gamma)to""_(Z-1)B^(A-4)`
