| Abstract: | Measurements of the spin-spin effect, σss in the total cross section for polarized neutrons on polarized 165Ho are reported at neutron energies of 0.4 and 1.0 MeV. The absence of an observable effect at 1.0 MeV is in contradiction with a recently reported experimental result. The results of an improved theoretical calculation of σss for neutron energies below 8 MeV are presented and used with the new experimental data to obtain the new limit Vss < 300 keV for the strength of the spin-spin potential. |
