| 摘 要： | The reaction cross section of 17B on 12C 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 (Rrms) was deduced to be (2.92±0.10)fm, while the Rrms of the core and the valence neutron distribution are 2.28fm and 5.98fm respectively. Assuming a ``core plus 2n' structure in 17B, the mixed configuration of (2s1/2) and (1d5/2) of the valence neutrons is studied and the
