Example Sentences

"We are aware from previous literature that the dominant thermal fission process for 235U is binary fission, which leads to the emission of two heavy nuclear fragments together with 2.4 neutrons, on average. But there is a 0.2% probability of ternary fission, in which light nuclear fragments are emitted. We, therefore, chose this route for our experiment under the assumption that the hypothetically bound tetraneutron could be a ternary particle in uranium fission," explains Dr. Fujioka.
