Description

Measurements of transverse attenuation lengths were made above the external target at KEK 12 GeV proton synchrotron using activation detectors. Evaluated attenuation lengths for high energy neutrons in paraffin, heavy concrete and iron shields are (133 +- 16), (163 +- 7) and (188 +- 12)g/cm2, respectively. These values are discussed in relation with the inelastic mean free paths. (orig.)
