# A neutron generator uses an (source, such as radium, to bombard beryllium, inducing the reaction 4 He + 9 Be → 12 C + n . Such neutron sources are called RaBe sources, 0r PuBe sources if they use plutonium to get the (s. Calculate the energy output of the reaction in MeV.

To determine

The energy output of the given reaction

Explanation

Given info:

â€ƒâ€ƒmHe=4.002603â€‰u

â€ƒâ€ƒmBe=9.012182u

â€ƒâ€ƒmc=12.00000â€‰u

â€ƒâ€ƒmn=1.008665â€‰u

Formula used:

The output energy can be determined by using Einstein's energy relation as

â€ƒâ€ƒE=Î”mâ€‰c2 .

â€ƒâ€ƒE=massâ€‰ofâ€‰reactant-massâ€‰ofâ€‰productâ€‰Ã—c2
