The synthesis of superheavy element evaporation residues is described by the product of the capture cross section, fusion probability, and survival probability. Capture cross sections are moderately well known. The fusion probability is the least known with many uncertainties. The formalism for the survival probability is known, but the parameters...
Recent experiments have advanced the current understanding of multi-nucleon transfer(MNT) reactions. Within nuclear science, most nuclear reaction experiments consist of a stationary target material, that is then bombarded by a moving projectile. Overall nuclear reactions can be used to produce a desired isotope. In the case of this particular study...
The yields of 235 projectile-like and target-like fragments from the interaction of ¹³⁶Xe with a thick target of ²⁰⁸Pb at a center-of-mass energy, E[subscript cm], of 450 MeV were measured using γ-γ-γ coincidence data from Gammasphere and off-line γ-ray spectroscopy. The results give an expansive picture of the production cross...
The atmospheric trace element abundances associated with
several major sources of air pollution in Western Oregon, such as the
paper industry, the metallurgical processing industry, the plywood
industry and agricultural field burning have been measured by instrumental
neutron activation analysis (INAA). Air samples were collected
directly from industrial stacks and...
¹³⁰ Sn and ¹²⁸Sn were separated from mixed fission products.
The decay of these isotopes were studied with Ge(Li),
LEPS, and plastic scintillator detector systems in single
and two parameter coincidence modes. The decay scheme constructed
for ¹²⁸Sn decay has levels at 0.0 (5+), 45.7 (4+),
77.8 (3+), 152.9 (2+),...
The atmospheric trace element abundances associated with "indoor"
and '"outdoor" air particulate have been measured for university chemistry
laboratories, typical homes, modern office buildings, hospital and
automobile repair garages in a rural setting (Corvallis, Oregon) and
modern office buildings in an urban setting (Portland, Oregon). Samples
of atmospheric particulate matter...
