3-4: a) Diabatic contributions <strong>of</strong> protons and neutrons for the systems Figure 90 + Zr 90Zr line) and (solid 96 + Zr 96 (dotted lines). Diabatic potentials for the systems b) Zr 90 + Zr 90Zr line) and (solid 96 + Zr 96 (dotted line) and c) Zr 130Xe+ 130 (solid line) and Xe 136Xe+ 136 Xe line). The nuclei are assumed as spherical with ε =0.74. (dotted 31
3-5: Diabatic potentials for the systems Figure 100Mo+ 100 (dotted line) and Mo 110Pd+ 110 Pd line). The phenomenological double folding potential for the system (solid 110 + Pd 110 is Pd by the dashed-dotted line. The discrepancy between this potential and the diabatic shown becomes smaller if, by starting at the minimum <strong>of</strong> the pocket, the neck parameter ε is one diminished with decreasing λ (dashed line for 110 Pd+ 110 Pd). 3-6: Diabatic potentials as a function <strong>of</strong> ε for the system Figure 110Pd+ 110 at λ =1.34 and Pd 1.56. 32
