'''<sup>6</sup>Li(D,α)α''' (sing bentuké sing dipadataké)
== Energi ==
Kanggo ngitung energi kang dikasilaké, perubahan massa isotop sadhurunglan sawisé reaksi nuklir kudu dietung. Gunggungé massa kang ilang, diping karo kuadrat kecepatan cahaya; hasilé padha karo energi kang ditokaké nalika reaksi.
(dekeng [[Tabel isotop]])
massa isotop '''Lithium-6''' : 6,015122795
massa isotop '''Deuterium''' : 2,0141017778
massa isotop '''Helium-4''' : 4,00260325415
'''Lithium-6 + Deuterium -> Helium-4 + Helium-4'''
'''6,015122795 + 2,0141017778 -> 4,00260325415 + 4,00260325415'''
'''8,0292245728 -> 8,0052065083'''
Massa kang ilang: 8,0292245728 - 8,0052065083 = 0,0240180645 u ('''0,3'''%)
(dibulatké)
'''E = mc''<sup>2</sup>'''
E = mc<sup>2</sup> = 1[[satuan massa atom|u]] x c<sup>2</sup>
= 1,660538782×10<sup>−27</sup> kg x (299.792.458 m/s)<sup>2</sup>
= 149241782981582746,248171448×10<sup>−27</sup> Kg m<sup>2</sup>/s<sup>2</sup>
= 149241782981582746,248171448×10<sup>−27</sup> [[Joule|J]]
= 931494003,23310656815183435498209 [[elektronvolt|ev]]
= 931,49 Mev (dibulatké)
Dadi, massa 1u = 931,49 Mev
E = mc<sup>2</sup> = 1 Kg x c<sup>2</sup>
= 1 kg x (299.792.458 m/s)<sup>2</sup>
= 89875517873681764 Kg m<sup>2</sup>/s<sup>2</sup>
= 89875517873681764 [[Joule|J]]
= 89,875 PJ (dibulatké)
Dadi, massa 1 Kg = 89,875 [[Awalan_SI|P]][[Joule|J]]
