2 | Angular distributions for elastic scattering of nucleons are taken as closely as |
---|
3 | possible from experimental data, i.e. from the result of phase-shift analysis. |
---|
4 | They are derived from differential cross sections obtained from the SAID |
---|
5 | database, R. Arndt, 1998. |

7 | Final states are derived by sampling from tables |
---|
8 | of the cumulative distribution function of the centre-of-mass scattering |
---|
9 | angle, tabulated for a discrete set of lab kinetic energies from |
---|
10 | 10 MeV to 1200 MeV. The CDF's are tabulated at 1 degree intervals and |
---|
11 | sampling is done using bi-linear interpolation in energy and |
---|
12 | CDF values. Coulomb effects are taken into consideration for pp scattering. |
