We can understand why 235u is readily fissionable, and 238u is not, by usingthe following calculation.
(a) find the energy difference between 235u + nand 236u. we can regard this as the "excitation energy" of 236u.
(b) repeat (a) for 238u + nand 239u.(c) (2 pts) comparing your results for (a) and (b), explain why 235u will fission with very low energy neutrons, while 238u requires fast neutrons of 1 to 2mev of energy to fission.

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
