The total kinetic energy (TKE) in the fast neutron induced fission of 237Np was measured for neutron energies from En = 2.6 – 45.7 MeV at the LANSCE- WNR facility. The postTKE release decreases non-linearly with increasing incident neutron energy and can be represented as TKE(MeV) = (169.365 ± 1.551)...
The nuclear reaction ¹⁰⁰Mo(¹²⁴Sn,xn)[superscript 224-x]U has been carried out at E[subscript cot] of 578 MeV and 634 MeV using the facilities and equipment at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL) in order to initiate the search for the inverse fission of uranium. Reference...
The atmospheric trace element abundances associated with slash
burning have been measured by instrumental neutron activation analysis
(INAA). On site ground level samples were collected during the slash
burning season using high volume samplers and a cascade impactor. In
addition to the air samples, soil, wood and ashed wood samples...
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
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...
The production cross sections for a number of target fragments
formed by the reactions of 42- and 21- GeV²⁰ Ne and 28 GeV p with ¹⁸¹Ta have been measured. The target fragment radioactivities were
measured by off-line gamma-ray spectroscopy. Details of the measurement
as well as the calculation of the...
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 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...
