Abstract
We did the Harris-Nesbet algebraic close-coupling calculation for positron-hydrogen scattering at low energies with the (1{ital s},2{ital s})H-(1{ital s},2{ital s})Ps, (1{ital s},2{ital s},2{ital p})H-(1{ital s},2{ital s})Ps, and (1{ital s},2{ital s},2{ital p})H-(1{ital s},2{ital s},2{ital p})Ps coupling schemes. Cross sections of elastic scattering, positronium formation, and Ps(1{ital s})-{ital p} elastic scattering were obtained for {ital L}=0,1,2,3,4,5,6 partial waves. The integrated cross sections for the relevant processes were then estimated. We compared our six-state close-coupling results with the ones calculated by solving the Lippmann-Schwinger coupled equations in momentum space. Many special features were seen in these cross sections.
