**Rigidity-Energy Converter**

This page enables users to convert, for different particles as electrons and ions, the Rgidity to Kinetic Energy per Nucleons and viceversa. The conversion is performed using the following formula:

\begin{equation}

R=\frac{A}{Z}\cdot\sqrt{T^{2}+2TT_{0}}

\end{equation}

Where \(R\) is the Rigidity, \(A\) is the mass number, \(Z\) is the charge, \(T\) is the kinetic energy per nucelon, \(T_{0}\) is the rest energy per nucelon.

To run the code follow this link:

## Input Parameters
