Well, I found that it's due the contribution of other states. In other words, for energies below 1 MeV, ##^3\mathrm{S}_1## and ##^1\mathrm{S}_0## states have more contribution rather than ##\ell = 1,2,3,...## And, between 100 to 350 MeV, triplet and singlet states have less contribution than...
Well, I'm simulating a neutron-proton scattering phase shift. The equation that I solve numerically is the Phase function method and is
$$ \frac{d}{dr}[\delta_{i+1}] = \frac{2\mu}{\hbar^2}\frac{V(r)}{k^2}\sin(kr + \delta_i)$$
##\delta_i## is the phase shift for triplet and singlet state, ##\mu##...
I'm trying to solve an ED numerically, but before to doing it I try to understand the system physically according to nuclear scale. In most books and articles use MeV for energy and mass energy and fm to represent distances and phase shift of wave functions are in radians or degree. But when I...
Ohhhhh, it means that is another kind of problem. I thought that the problem can be solved with circular motion, but I didn't consider the orbital motion and the influence of the gravitational force. Thanks a lot
