【 摘 要 】

Angular distribution for the inelastic scattering of 28 MeV6Li on76Ge was measured using the Sao Paulo PelletronEngeSplit-pole Spectrograph facility. The coulomb-nuclear interference (CNI) analysis was applied to the first quadrupole state transition. The values of CL= δCL/δNL, the ratio of charge to isoscalardeformation lengths, and of (δNL02were extracted through the comparison of experimental and DWBA-DOMP predicted cross section. The ratio of reduced charge to isoscalartransition probabilities, B(EL) to B(ISL) respectively, are related to the square of the parameter CLand were thus obtained with the advantage of scale uncertainties cancellation. The value of C2= 1.10(2) obtained indicate a slight predominance of the protons relative to the neutrons for76Ge.
