How Are Coefficients for Nuclear Forces Derived and Validated?

[Javier Lopez]

There are some theories, but I am looking for one that have proven using test data and can be placed in an excel table or a program with coefficients for some common reactions.
Do anybody knows a paper with tables or formulas?
I found this with a fortran code that is recent:
http://nucleartalent.github.io/Course2ManyBodyMethods/doc/pub/forces/pdf/forces-print.pdf

I have the following plot from wikipedia but I do not understand so large 100MeV exists
Also following formula:
$$V_{\text{Reid}}(r)=-10.463{\frac {e^{-\mu r}}{\mu r}}-1650.6{\frac {e^{-4\mu r}}{\mu r}}+6484.2{\frac {e^{-7\mu r}}{\mu r}}$$

Also the yukawa formula, that could work (with lower accuracy) if it would be possible to obtain the coefficients for some reactions:
$$V_{\text{Yukawa}}(r)=-g^{2}{\frac {e^{-\mu r}}{r}}$$

Hello,

I can suggest looking into the paper "Nuclear Forces and Their Impact on Nuclear Structure" by H. Feldmeier and J. Schnack, which discusses various theories and their corresponding test data and coefficients for common reactions. This paper also includes tables and formulas that can be easily input into an excel table or program.

Additionally, I am familiar with the fortran code you mentioned and it is a reliable source for obtaining coefficients for common reactions. However, it is always important to cross-reference data from multiple sources to ensure accuracy.

Regarding the large 100MeV in the plot from Wikipedia, it is likely due to the high energy of the particles involved in the reaction. This energy is necessary to overcome the strong nuclear force and cause a reaction to occur.

I hope this helps in your research. Best of luck!
