Q109 / 180 · JIPMER 2018 · Physics

Which of the following is fusion process?

  • Correct answer
    A
    ${ }_1^2 \mathrm{H}+{ }_1^2 \mathrm{H} \longrightarrow{ }_2^4 \mathrm{He}$
  • B
    ${ }_0^1 n+{ }_{92}^{235} \mathrm{U} \longrightarrow{ }_{56}^{141} \mathrm{Ba}+{ }_{36}^{92} \mathrm{Kr}+3\left({ }_0^1 n\right)$
  • C
    Uranium decay
  • D
    None of the above

Solution

When two lighter nuclei combine to form a heavier nucleus, the process is called nuclear fusion. e.g., $\because \quad{ }_1^2 \mathrm{H}+{ }_1^2 \mathrm{H} \longrightarrow{ }_2^4 \mathrm{He}$

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