Abstract

The effects of specific distortion in the d + α system are examined. The result shows that, because of the high compressibility of the deuteron cluster, these effects are very important in this system. By properly considering such effects within the resonating-group framework, it is noted that one can obtain a satisfactory description of the experimental data on differential cross sections, vector and tensor polarizations, and the effective nucleon-nucleon (NN) potential required is very similar to those required in the p + α, 3H + α, and α + α systems. With the resultant wave function, the charge form factor of 6Li is also studied for q2 values up to about 14 fm−2. Here one finds that there is a good agreement with experiment in the higher-q2 region; in particular, the position of the diffraction minimum and the height of the diffraction maximum are well reproduced. The calculated charge rms radius, however, is only 2.31 fm, which is somewhat too small.
