The radioactive isotope `""_(27)^(60)Co` which is used in the treatment of cancer can be made by (n,p) reaction. For this reaction the target nucleus is

Options

A. `""_(27)^(60)Co`
B. `""_(28)^(59)Ni`
C. `""_(28)^(59)Co`
D. `""_(28)^(60)Ni`

Answer

D

Explanation

`""_(a)X^(b)+""_(0)n^(1) to ""_(1)P^(1)+ ""_(27)Co^(60)`
`therefore a=1+ 27 =28`
and b=1 + 60-1=60
`therefore ""_(a)X^(b)=""_(28)Ni^(60)`
