Please explain to me how can I calculate the deuteron density using the Gaussian density and can you use the Mathematica program to solve it

III. DENSITY DISTRIBUTIONS OF THE PROJECTILE AND TARGET NUCLEI A. Densities of the deuteron projectile 1. Gauss density The first density distribution used for the deuteron nucleus is the Gauss (G) density, which is parameterized as follows: (r)=0exp(r2) where 0=0.0992fm3 and =0.424fm2 [24]. This density has been denoted as D1 in our calculations. III. DENSITY DISTRIBUTIONS OF THE PROJECTILE AND TARGET NUCLEI A. Densities of the deuteron projectile 1.
