Abstract：

The reaction cross section of¹⁷B on¹²C target at (43.7±2.4)MeV/u has been measured at the Radioactive Ion Beam Line in Lanzhou (RIBLL). The root-mean-square matter radius (R_rms) was deduced to be (2.92±0.10)fm, while the R_rmsof the core and the valence neutron distribution are 2.28fm and 5.98fm respectively. Assuming a ``core plus 2n'' structure in¹⁷B, the mixed configuration of (2s_1/2) and (1d_5/2) of the valence neutrons is studied and the
s-wave spectroscopic factor is found to be (80±21)%.
