Ramayya of Vanderbilt University in Nashville and his collaborators have discovered that, in addition to normal spontaneous fission, the isotope californium-252 occasionally splits in two in such a way that no neutrons are released.
Ramayya and his coworkers have also found that californium-252 sometimes breaks into three fragments--two of moderate size and one as small as a helium nucleus (or alpha particle).
The key step involves using an essentially nondestructive form of mass spectrometry based on the radioactive isotope californium-252. Fission fragments from the isotope's disintegration bombard the film, intensely heating the surface and causing molecules to ionize and vaporize.
