Langevin approach developed by an international team of researchers, including members from Science Tokyo, accurately reproduces complex fission fragment distributions and kinetic energies in ...

A five-dimensional model has successfully predicted the asymmetric fission of mercury isotopes, offering new insights into ...

Physicists have solved a long-standing puzzle about mercury’s nuclear fission by using a five-dimensional model that ...

We assumed that the fission fragments had an exhaust velocity of 0.05 c (Isp=1.5 million), to obtain a fuel fraction 3% that of the rocket. We then added the mass of the fuel to the mass of the rocket ...

Fission Fragment rockets are several proposed nuclear rocket designs made since the 1980s with the highest potential theoretical top speed. The fission-fragment rocket is a rocket engine design that ...

Subtle quantum effects within atomic nuclei can dramatically affect how some nuclei break apart. By studying 100 isotopes with masses below that of lead, an international team of physicists uncovered ...

State-of-the-art theoretical models try to explain the observed fission properties, like how much energy is released, the number of neutrons emitted and the masses of the fission fragments.

In such cases, Wilson says, the incoming energy might potentially lead to pre-scission influences on the spinning of the resulting fragments. “Even though fission was discovered 80 years ago, it ...
