Abstract：

The mirror nuclei¹²N and¹²B are separated by the Radioactive Ion Beam Line in Lanzhou (RIBLL) at HIRFL from the breakup of 78.6 MeV/u¹⁴N on a Be target. The total reaction cross-sections of¹²N at 34.9 MeV/u and¹²B at 54.4 MeV/u on a Si target have been measured by using the transmission method. Assuming¹²N consists of a¹¹C core plus one halo proton, the excitation function of¹²N and¹²B on a Si target and a C target were calculated with the Glauber model. It can fit the experimental data very well. The characteristic halo structure for¹²N was found with a large diffusion of the protons density distribution.
