3/1H (tritium) can be produced in water surrounding a strong source of neutrons, such as that occuring in nuclear reactors. One of the ways tritium can form is via neutron capture by deuterium.

Part A

Write down the equation for this capture reaction.

Part B

Tritium has a half-life of 12.33 years. What percentage of a sample containing 31H will remain after exactly 3 years?

Part C

Determine the gamma-ray energy emitted during the capture (assuming the tritium ends up in its ground state and the incoming neutron kinetic energy is negligible).

Part D

Write down the reaction for the subsequent beta decay of the tritium.

Part E

Determine the stable daughter identity.

Part F

If all the energy released in the beta decay went into the beta particle, determine its energy.
