The nuclear reaction is:
23892U + n-------23992U-------23993Np + e--------23994Pu + e
The other product formed when curium-242 is bombarded with an alpha particle is uranium-238.
There are many isotopes for uranium, the most abundant of them in nature are:Uranium- 234, having 142 neutron and 92 protonUranium- 235, having 143 neutron and 92 protonUranium- 238, having 146 neutron and 92 protonThe abundance of these three isotopes in natural uranium is:Uranium-234: 0.006 %Uranium-235: 0.720 %Uranium-238: 99.274 %
They are many but the most famous three are: uranium-233, Uranium-235, and Plutonium-239.Another answerUranium-235, uranium-238, and plutonium-239 are all capable of undergoing neutron induced fission. Actually there are other isotopes that also do this, but they are not commonly used as fuel.
Uranium, atomic number 92, has several isotopes, and 238U is just one of them. Remember that a nucleon is one of the particles that make up the nucleus of an atom, and that means a proton or a neutron. In the case of this isotope of uranium, it has the 92 protons we'd expect for uranium, and it has 146 neutrons in its nucleus along with those protons. That's 238 necleons in the nucleus if 238U. Wikipedia has more information on uranium and on the nucleon, and links are provided.
92U-238 + 0n ------92U-239----- β ----- 93Np-239------ β --------94Pu-239
The other product formed when curium-242 is bombarded with an alpha particle is uranium-238.
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.

uranium 238 is a fast neutron absorber the answer is correct but for more explanation:- when uranium 238 is bombard by neutron >>> uranium 238 , undergoes B decay>>>Np 239 ,undergoes B decay >>> Pu 239 finally undergoes alpha decay >>> fissile U
The resulting isotope is uranium 239 with a half life of 23.5 minutes (beta desintegration).

When U-238 absorbs a fast neutron it forms plutonium-239
a free neutron can trigger the split of a particle like uranium 238. It will produce a smaller atom (eg. proctantium), a beta particle and energy.
The most common isotope of uranium is uranium-238. The atomic number of uranium is 92, which means it contains 92 protons. To calculate the number of neutrons, subtract the number of protons from the mass number 238. No. of neutrons in 238U = 238 - 92 = 146

Uranium-235 is more explosive than uranium-238. This is because uranium-235 is fissile, meaning it can sustain a chain reaction of nuclear fission, which releases a large amount of energy. Uranium-238 is not fissile and requires a neutron source to undergo fission.
Uranium-234 become protactinium by emission of a beta particle. A proton is transformed in a neutron.
