To create a Kurie plot for Sr-90 data, the y-axis values should be calculated as the square root of the frequency, which is derived from counts per energy value. The relationship between energy and momentum is acknowledged, but the x-axis will represent energy. Clarification is sought on specific functions such as N(E), F(Z,E), and S(E), which are essential for accurate plotting. These functions may require reference tables for proper interpretation. Understanding these terms is crucial for successfully generating the Kurie plot.

I am trying to make a Kurie plot for Sr-90 data collected. I have my data in counts per energy value, and I know the length of time that the measurement was taken for. How do I compute the y-axis values to produce a Kurie plot? Most of what I have read involves momentum; is there a way to get it from energy and counts?
Thanks

The y-axis is just the square root of the frequency. Energy and momentum have a direct relation, but the x-axis is energy anyway.

By frequency, you mean the rate of returns from the detector? i.e. counts/min?
 
I just Googled "Kurie plot" . 7 of the first 10 plots had their axes labeled. This obviously isn't working for you - can you explain why not?

Thanks. Yes, they have them labelled with $$\sqrt \frac{N(E)}{pEF(Z, E)S(E)}$$

I am not sure what ##N(E)##, ##F(Z,E)##, and ##S(E)## refer to as they are functions. I tried searching for them, and I couldn't determine what the functions are. The closest I found was something that mentioned ##F(Z,E)## is often looked up in some table.

Some help with what the terms under the root sign would be greatly appreciated.
 
Theoretical physicist C.N. Yang died at the age of 103 years on October 18, 2025. He is the Yang in Yang-Mills theory, which he and his collaborators devised in 1953, which is a generic quantum field theory that is used by scientists to study amplitudes (i.e. vector probabilities) that are foundational in all Standard Model processes and most quantum gravity theories. He also won a Nobel prize in 1957 for his work on CP violation. (I didn't see the post in General Discussions at PF on his...
