Predictions of the properties of nuclides near the extreme limits of nuclear stability provide a measure of our understanding of the fundamental properties of matter and the fission process. Predictions of an ''island of stability'' of long-lived sup

In November 1989, we carried out a measurement of the fission cross section of 247Cm, 250Cf, and 254Es on the Rensselaer Intense Neutron Source (RINS) at Rensselaer Polytechnic Institute (RPI). In July 1990, we carried out a second measurement, using

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

New attempts have been made to synthesize superheavy elements (SHE) by nuclear reactions that may possibly form the products at low excitation energies. Survival of the superheavy elements would then be enhanced because of reduced losses from prompt

The fragment energies of about 725 coincidence events have now been observed in the spontaneous fissipn (SF) decay of 105-mm 259Md since its discovery in 1977. The fission of 2D9Md is characterized by a symmetric mass distribution, similar to those o

The α-decay of 255Md,256Md and257Md has been studied following production of these isotopes in a series of helium-ion bombardments of an einsteinium target. The mendelevium was collected as the atoms recoiled from the target during bombardment. Foll

Excitation functions and angular distributions have been measured for the fission of 232Th, 238U, 244Pu and 248Cm induced by 86Kr and 136Xe ions at energies in the vicinity of the Coulomb barrier. No large differences as a function of either target o
