Proton bombardment of plutonium-239 (z = 94) will result in the production of a neutron and which of the following nuclides?

What are your options?

 If I remember correctly the result of proton bombardment is the addition if a proton to the nucleus. This means Z will increase by 1 to 95 (Americium, Am). Because the proton is just replacing the neutron, the mass won't change (i.e. it will still be 239).
