Re: Answer keys w/ explanation?

Hello, Sorry about the late reply I had family things to attend to, it is the summer after all. After considering what Rich and Dennis said I crunched some numbers. 1.0% of 1 cm^2 is 0.01 cm^2. From what I understand you want me to find how many nuclei fit in the 0.01 cm^2 which can also be written ...

Re: Answer keys w/ explanation?

The method i'm using now is off of a website that talks about cross section and scattering. On there, there is an equation that represents this. What I thought of doing was rearranging it so i]I can solve for the thickness. Here is the website: http://hyperphysics.phy-astr.gsu.edu/hbase/Nuclear/cros...

Re: Answer keys w/ explanation?

Hello, In order to find the atomic number density I used the equation you have linked: N=ρNa/M The values I used where ρ = 16g/cm^3; Na = 6.022 x 10^23 nuclei/mole; and M = 181 The value I received for N = 5.32 x 10^22 atoms of tantalum/cm^3 The cubed root of this value is approximately 3.76 x 10^7 ...

Re: Answer keys w/ explanation?

Just to start this rolling, I will ask the first question from the book Introductory Nuclear Physics by David Halliday 2nd edition. The question is from page 22 of the first chapter Basic Nuclear Concepts A Tantalum foil (A=181) has 1.0% of its projected area blocked out by nuclei. How thick is the ...
