A proton of kinetic energy 0.42 x 10-11 J is fired at a stationary oxygen-18 which has a binding energy of 2.35 x 10-11 J. This reaction produces flourine-18 of binding energy 2.30 x 10-11 J with the production of a neutron and gamma ray.
Q1) Explain why the high energy proton is required.
Q2) Estimate the energy of the gamma photon
The Attempt at a Solution
Q1) - is it because energy is required to turn a neutron into a proton inside the nucleus? Or would I have to talk about the bidning energy?
Q2) I am unsure if it is 0.05 x 10-11 J (difference in binding energy) or 0.37 x 10-11 J (the remaining kinetic energy of the proton (I am thinking this is more likely)
Some guidance/confirmation would be greatly appreciated!
