ocr: FUSION REACTION The fusion of atomic nuclei, resulting in the release of energy. Fusion energy is the basis for the radiation of stars, including the Sun. The process requires a remperarure of over 10 million degrees, and extremely high pres- sure. Continuous fusion is possible only if the elements taking part are completely ionized into plasma. The capacity of the Sun is C. 4 X 1026 In the fusion reaction inside a star, 4 hydro- watts. Colculations show that the Sun gen nuclei fuse into helium in the so-called loses 4 million tons of its mass each profon-profon reaction, with the result secon ...
