在70GeVIHEP加速器上测量了π±、K±介子、质子和反质子在动量为6.65GeV/c~60GeV/c的Li、Be、C、Al、铜、锡、铅和铀上的吸收截面。计算结果与Glauber多重散射模型的计算结果进行了比较。原子核半径可用原子量的幂函数R=r0A13来描述，其中r0=1.05±0.02fm。
Absorption cross sections for π±, K±mesons, protons and antiprotons on Li, Be, C, Al, Cu, Sn, Pb and U in the momentum range from 6.65 to 60 GeV/c are measured at the 70 GeV IHEP accelerator. The cross sections are compared with calculations using the Glauber multiple-scattering model. Nucleus radii are found to be described by a power dependence on atomic weight R= r 0 A 1 3, where r 0= 1.05±0.02 fm.
