    I Fission of 238U with high energy neutrons & other questions

    Hi, I have a question related to 238U. I know of course that it can fission with neutrons above 1 MeV, but there is a elevated risk it would absorb the neutron and produce 239Pu instead. Let's assume you have a ram of metallic 238U, with perhaps 0,7% 235U, and that you collide it very very...

    Light Collection Efficiency for Liquid Scintillation Detecto

    How do I calculate the light yield and light collection efficiency of a liquid scintillation detector? Couls someone give me a formula for that? What data do I need to calculate it? THanks a bunch!

    Liquid Scintillation Counter w/ fast neutron detectin isotop

    I'm trying to make a LSC with U-238 (non-aqueous form) dipped in the scintillating cocktail to detect fast neutrons (no thermals or epithermals, only fast) from a Cf-252 source. How do I calculate the wavelength emerging from the cocktail (assuming U-238 does not react with the cocktail)? Also...
