Question
What is obtained by fusion of two deuterons?
✓
Answer
By fusion of two deuterons, either tritium $\big(^3_1\text{H}\big)$ or an isotope of helium $\big(^3_1\text{He}\big)$ is obtained with release of energy. The reactions are:
$^2_1\text{H}\ +\ ^2_1\text{H}\ \rightarrow\ ^3_1\text{H}\ +\ ^1_1\text{H}\ +\ 4.03\text{ MeV}\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ^\text{(tritium)}$
$^2_1\text{H}\ +\ ^2_1\text{H}\ \rightarrow\ ^3_1\text{He}+^1_0\text{n}\ +\ 3.27\text{ MeV}\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ^\text{(isotope of helium)}$
