| Anotace | Energy integrated reaction cross-section measurements of around sixty neutron-rich nuclei covering the region of closed shells N = 20 and N = 28 were performed at intermediate energy (30-65 A.MeV) using direct method. In this experiment, silicon detectors were used as active targets. The reduced strong absorption radii, r(0)(2), for 19 new nuclei (F-27, Ne-27,Ne-30, Na-33, Mg-28,Mg-34-35, Al36-38, Si38-40, P41-42, S42-44 and Cl-45) are deduced for the first time. An additional 60 radii, also measured in this experiment, are compared to results from literature. A new quadratic parametrization is proposed for the nuclear radius as a function of the isospin in the region of closed shells N = 8 and N = 28. According to this parametrization, the skin effect is well reproduced and anomalous behaviour on the radii are observed in N-23, Ne-29, Na-33, Mg-35, S-44, Cl-45 and Ar-45 nuclei.
