I'm supose to do a project on it but I don't understand it.
Fritz and Otto discovered that an isotope of barium was produced by neutron bombardment of uranium with netrons. Can anyone tell me why and how they did this?

It must have been reaction of U-235 with neutrons to produce fission. Ba has at. no. 56, which is 60% of the value of U. Also, the atomic weight of Ba is 58% of U-235. So something profound must have occurred, different from alpha, beta, or positron decay. By Otto, do you mean Otto Hahn, who discovered U-235 fission along with Lisa Meitner?

As Steve has pointed out, the experiment is one that proved that fission had occurred. It was the first example of such and the episodes here all were grouped around the Nobel awarded to Fermi in 1938. Otto Hahn and Felix Strassman spoke of it in their article in December of that year in Naturwissenschaften where they finally stated that the result was "contrary to all previous experience in nuclear physics".
