We have measured the mass and total kinetic energy distributions from the spontaneous fission of 252No, 254No, 256[104] and 258[104]. The results, in combination with earlier measurements for 256No, 258No and 262No, show a sharp transition from asymm

We investigated the nuclear properties of several mendelevium isotopes produced in the reactions of heavy ions with 245Esg. We measured the alpha particles, spontaneous fissions (SF), and photons emitted by counting samples resulting from chemical an

We have made the first measurement of the number of neutrons emitted from the spontaneous fission of a nuclide in which very high fragment energies dominate the fission process. In bombardments of {sup 254}Es, we produced a large sample of 28-d {sup

We have measured cross sections for the formation of actinide transfer products in the reaction of 72-MeV $^{13}\mathrm{C}$ projectiles with $^{254}\mathrm{Es}^{\mathrm{g}}$ targets. The pattern of nuclide yields is similar to those observed in the r

The neutron-induced fission cross sections of Cm-244, Cm-246, and Cm-248 which were measured with the RINS lead spectrometer system at RPI have been analyzed for intermediate structure. Gross structure is observed in Cm-244 near 200, 400, 800, and 20

The 103-min isotope $^{259}\mathrm{Md}$ has been identified as the daughter of an electron-capture decay branch of $^{259}\mathrm{No}$ produced via the $^{248}\mathrm{Cm}(^{18}\mathrm{O},\ensuremath{\alpha} 3n)$ reaction. Chemical separations were us

We have extended the search for superheavy elements in an experiment designed to condense and detect volatile superheavy elements with half-lives between one and 10 7 s. None were detected, however, a large region of very low cross sections and short

We report radiochemically determined cross sections for the heaviest known actinides produced in transfer reactions of /sup 16,18/O and /sup 22/Ne with /sup 254/Es as a target. A comparison with data for similar transfers from /sup 248/Cm targets is
