We use the above definitions in Fig. 7 to compare calculated heavy and light fission-fragment masses, based on valley properties at Q 2 = 99 b, to experimental data for the mean positions of the ...

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

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

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

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 ...

A five-dimensional (5D) Langevin approach developed by an international team of researchers, including members from Science Tokyo, accurately reproduces complex fission fragment distributions and ...
