| Popis: |
Comparisons of exact finite-range (EFR) DWBA calculations and zero-range (ZR) calculations are presented for the cross sections and analysing powers of the 32 S ( 3 He , 4 He ) 31 S reaction to the ground state ( 1 2 + ), 1.25 MeV ( 3 2 + ) and 2.23 MeV ( 5 2 + ) states. The data for the 3 2 + and 5 2 + states are quite well fitted and show the characteristic j-dependence of the analysing powers. Only small differences between the EFR and ZR calculations are seen. The analysing power data for the 1 2 ± state are poorly fitted by the EFR or ZR calculations but better agreement is obtained when the coupling to other levels is included in a coupled channel Born approximation (CCBA) calculation. |
