“…Minimum distance S between the two nuclear surfaces needed to ensure pure Coulomb excitation versus the sum of the matter half-density radii Cp+ Cr of projectile and target nucleus. The experimental data for lighter systems are taken from [6][7][8][9][10] In Fig. 5 the separation S is plotted versus Cp + CT for our studied systems (206, 2OSpb and 152Sm ' 16OGd ' 232Th) and previous experimental data [6-10] using other projectile-target combinations.…”

In a systematic study of nucleon transfer reactions accompanied by Coulomb excitation we have bombarded 152Sm, 16~ and 232Th with 206,208pb beams at incident energies close to the Coulomb barrier. Particle-gamma coincidence techniques were used to identify excited states of reaction products populated through inelastic scattering and in nucleon transfer reactions. One-neutron stripping and pick-up reactions on 152Sm were observed leading to known states of the rotation aligned il 3/2-bands in 1538m and 15 l Sm" In the 16~ + 2o6,208pb systems no significant population of low lying states of product nuclei was found in the nucleon-transfer channels. Large cross sections were observed for one-and two-neutron pick-up from 232Th at an incident energy of 6.4 MeV/u. Around the grazing angle they are of the same order of magnitude as the cross section measured for inelastic scattering. The results are analyzed in the framework of semiclassical models.

“…in inelastic scattering experiments far above the Coulomb-barrier. The elastic and inelastic scattering of 4He-particles has widely been used to excite collective nuclear states in light nuclei [3] and in nuclei in the rare earth region [4]. The strong absorption of the 4He-particles in nuclear matter makes 4He-* Now at 1.…”

The angular distributions of the elastic 4He-scattering on 2~and the elastic and inelastic ~He-scattering on 232Th and 234'236'238U at E4He=50MeV were measured between 20 ~ and 60 ~ The 4He-particles were detected with a position sensitive detector in the focal plane of a split-pole spectrograph. The aim was to get data to determine the deformation parameters of the equilibrium states by coupled channels calculations.

“…Previous theoretical results have given no possibility of such values. The older experimental results [16][17][18] where already well reproduced [5] and we hope to get no worse agreement in this new approach. The aim of the present paper is to add our simplified consistency condition to the shell correction method and see what it gives in the rare earth region.…”

The theoretical calculations of multipole moments of even-even rare earth nuclei are presented. The potential energy surface is evaluated by the shell correction method. The condition ensuring the equality of the density distribution of the macroscopic liquid droplet part of the potential energy and the density generated by the single particle potential is added. A single particle Nilsson potential is used. New, less stiff potential surfaces versus e~ are obtained while the multipole moments calculated at the equilibrium deformations agree well with experimental data.
