Popis: 117 interactions of cosmic ray particles with aluminium nuclei have been studied. 101 showers containing no apparent unstable particles yielded the following multiplicities: $$\left\langle {n_s } \right\rangle = 7.3; \left\langle {n_s^ + } \right\rangle = 3.9; \left\langle {n_s^ - } \right\rangle = 2.7; \left\langle {n_s^ \pm } \right\rangle = 0.6.$$ . The momentum and angular distributions of the secondary particles were examined, and an attempt was made to study the momentum-angle correlation. The mean transverse momentum was 0.31 GeV/c, the RMS deviation about this mean being 0.23 GeV/c. A quantity related to the (U−pL) of the recoil nucleon was also investigated. 12 showers containing one V0 each and 1 shower containing two V0 particles were studied; this showed that the 117 showers contained; 29.5−11.0+14.0 Λ0 and 18.0−10.0+15.0 ϑ0 particles. 3 showers containing V± particles were also studied; one of them was probably a Ξ− particle.
