摘要

新的达勒姆光谱仪，火星，已经被用来研究宇宙射线介子在铁中的库仑散射，动量范围在10-70 GeV/c。观测到的均方根侧向位移与预测结果吻合良好，在统计误差范围内，最小动量为2%，最大动量为17%。在整个动量范围内，观测到的散射位移与期望的均方根散射位移之比为1.023+or 0.019。

Multiple scattering of cosmic ray muons in the range 10-70 GeV/c

The new Durham spectrograph, MARS, has been used to study the Coulomb scattering of cosmic ray muons in iron in the momentum range 10-70 GeV/c. The observed root mean square lateral displacement agrees well with that predicted to within the statistical errors, which range from 2% at the lowest momentum to 17% at the highest momentum. Averaged over the whole momentum range the ratio of observed to expected root mean square scattering displacement is 1.023+or-0.019.
