एक न्यूट्रॉन नाभिक `""_(3)^(6)"Li"` द्वारा अवशोषित किया जाता है जिससे अल्फा-कण उत्सर्जित होता है |
इस अभिक्रिया में विमुक्त ऊर्जा (MeV में) की गणना कीजिए |
दिया है - `m(""_(3)^(6)"Li")=6.0151212"u"`
`m_(n)("न्यूट्रॉन")=1.0086654"u"`
`m_(alpha)("अल्फा कण")=4.0026044"u"`
और m (ट्राइटन) `=3.0100000"u"`
`1u=931" MeV"//"c"^(2)` लीजिए |

Best answer
द्रव्यमान क्षति `DeltaM=m(""_(3)^(6)"Li")+m_(n)("न्यूट्रॉन")-m_(alpha)("अल्फा-कण")-m("ट्राइटन")`
`=6.01512126+1.0086654-(4.0026044+3.0100000)`
`=0.01118226u`
`:.` विमुक्त ऊर्जा `Q=Delta"Mc"^(2)=0.01118226"u"xx"c"^(2)`
`=0.01118226xx931" MeV"//"c"^(2)xx"c"^(2)`
`=10.41" MeV."`
