Textbook Problem

# Neutrons from a source (perhaps the one discussed in the preceding problem) bombard natural molybdenum, which is 24 percent 98Mo. What is the energy output of the reaction 98 Mo + n → 99 Mo + γ ? The mass of 98MB is given in Appendix A: Atomic Masses, and that of 99Mo is 98.907711 u.

To determine

The energy output of the given reaction

M98o+nM99o+γ

Explanation

Given info:

â€ƒâ€ƒmM98o=97.905406â€‰â€‰u

â€ƒâ€ƒmM99o=98.907711â€‰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
