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

  • A
    \({ }_{28}^{59} \mathrm{Ni}\)
  • B
    \({ }_{27}^{59} \mathrm{Co}\)
  • Correct answer
    C
    \({ }_{28}^{60} \mathrm{Ni}\)
  • D
    \({ }_{27}^{60} \mathrm{Co}\)

Solution

\([\mathrm{X}]+{ }_0^1 \mathrm{n} \rightarrow{ }_{27}^{60} \mathrm{Co}+{ }_1^1 \mathrm{H}\) Balancing the mass and atomic numbers on both sides \({ }_{28}^{60} \mathrm{X}+{ }_0^1 \mathrm{n} \rightarrow{ }_{27}^{60} \mathrm{Co}+{ }_1^1 \mathrm{H}\) Thus \(\mathrm{X}\) should be \({ }_{28}^{60} \mathrm{Ni}\)

Hence, the correct answer is option: 'C'.
