这篇总结性文章论述了由π-p,p-p,-p,γ-N作用产生奇异粒子及奇异粒子与核子相互作用实验方面目前的情况。它是上一篇文章“能量在10Bev以下的π-N,p-N和-N相互作用”的继续和补充。本文概括了最新的关于奇异粒子产生及作用的实验结果。并特别着重于讨论π-p作用产生奇异粒子及奇异粒子与核子相互作用的材料。对π-p作用,区分了近阈能区及高能区的现象,讨论了截面与角分布随能量变化的情况及产生过程中的极化现象,进行了振幅分析,同时列出了稀有事例的最新成果。对于实验数据比较少的p-p,-p及γ-N产生奇异粒子的作用作了简单的归纳。对奇异粒子与粒子相互作用,叙述了K-N作用的总截面、弹性散射、非弹性散射及不同的共振态。在弹性散射方面,研究了微分截面的角分布。在非弹性散射方面,我们看了各种非弹性过程及分枝比。对与π的共振态这一极为重要的现象所提出的二种解释作了叙述。最后还提出了一些问题,特别是对KKππ作用的看法,我们认为这也许是奇异粒子产生及作用中主要的过程。

A cloud chamber experiment is described, in which the angular distribution of secondary particles produced in nuclear interaction by high energy cosmic ray particles with paraffin has been studied. Sixty-four ns ≥4 events with average primary energy of 70 BeV have been analysed. The result shows that, in this energy region, the angular distribution in CMS is not isotropic but possesses maxima in the 0° and 180° directions; furthermore, there is already an appreciable fraction ( 20%) of the events with angular distribution exhibiting the features given by the "fire-ball" model.

The excitation functions of the Be9 (d,p0) Be10 reaction have been measured at θL = 135°? from Ed = 0.1 to 2.5 MeV, at θL = 95°? from Ed = 0.1 to 2.2 MeV and at θL = 112.5°? from Ed, = 0.5 to 2.5 MeV, respectively. By use of thicker targets (100-300 ?μ/cm2) and at Ed = 1.2 MeV, the absolute cross sections of the Be9(d, p0)Be10 reaction were measured at θL = 135°?and 112.5°;? the results obtained are: σp0(θL = 135°= 1.60 mb/st and σp0(θL = 112.5°=1.55 mb/st. Thus, the behaviours of the cross sections of all these five groups of outgoing particles have been obtained in this energy range. These experimental results are discussed to some extent.
