✦ Synopsis
The semiclassical distorted wave (SCDW) model of multistep direct processes is extended to calculate the double differential inclusive cross section (DDX) and the complete set of spin transfer coefficients (D ij ) at energies of 350-400 MeV, taking account of one-and two-step processes. The DDX for (p, p x) on 40 Ca at 392 MeV is calculated and compared with experimental data. The calculated D ij and the DDXs for (p, nx) on 12 C and 40 Ca at 346 MeV for the emission angle of 22 • are compared with the measured ones. Features of the calculated D ij , the contribution of twostep processes in particular, are discussed in terms of the comparison with those of the DDX. The calculated DDX and D ij are analyzed in terms of the choice of the bare NN force on which the effective interaction is based, the difference in the methods of the calculation of G matrices, and the in-medium modification of effective interactions.
