Question

The first nuclear reaction utilizing particle accelerators was performed by Cockroft and Watson. Accelerated protons were used to bombard lithium nuclei, producing the following reaction Since the masses of the particles involved in the reaction were well known, these results were used to obtain an early proof of the Einstein mass-energy relation. Find the Q value of the reaction. The mass of H is 1.00782 u. the mass of Li is 7.016 u. and the mass of He is 4.0026 u. 20.8976 MeV 17.3445 MeV 10.9098 MeV 172.453 MeV 6.7865 MeV 12.4532 MeV

Explanation / Answer

{[1.00782+7.016]-2*4.0026}*931.5=17.34Mev=Q value so option 2 is correct.
