A neutron hits U 235 which then splits into a Cs 140 atom (139.91728u), a Rb 93 atom (92.92204u), and several neutrons. How many grams of U 235 do we need to start with to produce 1.3 x 10^9 J?

U-236 is an important neutron poison in reactors that is created in uraniumbased fuels from U-235 capturing a neutron. Derive an expression for the time at which the peak U-236 concentration occurs. Note that not all neutron absorption by U-235 becomes U-236; some U-235 atoms fission.

On neutron-capture induced fission, 235 92U typically splits into two new “fission product” 92 nuclei with masses in the ratio 1:1.4. These are born with the same proton to neutron ratio as the original uranium, so they have too many neutrons to be stable at their mass number and are highly radioactive. Energy is released in two stages: first an intermediate or prompt release leading to radioactive fission products in their ground state; and then a much slower release via...

An atom of beryllium (m = 8.00 u) splits into two atoms of helium (m = 4.00 u) with the release of 92.2 keV of energy. Suppose the beryllium atom moved in the positive x direction and had a kinetic energy of 44.0 keV. One of the helium atoms is found to be moving in the positive x direction. Find the direction of motion of the second helium, and find the velocity of each of the two helium atoms. Solve...

1a Describe how thermal energy is obtained by fission, specifically when a U=235 atom is hit by a slow-motion neutron (less than 0.9 MeV). When one states that 200 MeV of energy are released by a fission event, what is the form of this energy? 1b. The energy released by fission is by the change in mass and Einstein’s equation (E=Δmc2). If the mass of one uranium 235 atom is 235.042924 amu and the mass of fission products is 234.92754...
