The Properties of U235 and U238: A Comparison

AI Thread Summary
U-235 and U-238 isotopes are chemically similar due to their identical electron configurations, but they differ significantly in nuclear properties. This distinction allows for their separation through methods like laser isotopic separation. Comprehensive information on their nuclear characteristics can be found in textbooks and resources from organizations like IAEA and NEA. Specific data, such as fast fission cross sections, can be accessed through dedicated databases like the one provided by the National Nuclear Data Center. Understanding these differences is crucial for applications in nuclear science and technology.

hi
Is there any document about the difference between U235 and U238 properties?
 
Engineering news on Phys.org
Chemically, isotopes are essentially indistinguishable - they have the name Z and same number of electrons, and the difference in mass of the nucleus doesn't cause a substantial difference in chemical properties, but there is just enough difference to separate the isotopes by laser isotopic separation.

The nuclear properties are quite different and these are published in many textbooks or available from IAEA/NEA and other sources.

For example - http://www.nndc.bnl.gov/sigma/index.jsp Just click on the element.
 
My guess is he is interested in fast fission cross sections...for pease! [sic]
 
Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
