摘要：

A new, simple, direct method for the measurement of reaction cross sections (sigma-R) is presented. The sigma-R for neutron-rich exotic nuclei were measured and the reduced strong absorption radii r0(2) were deduced. A strong isospin dependence of r0(2) was observed for measured isobars with masses from A = 10 up to A = 18. For heavier nuclei, this dependence is strongly reduced.
