ABSTRACT

We report the results of a research, in which we studied nuclear bursts in cosmic rays, developed with a counter-controlled cloud chamber at the Laboratorio della Testa Grigia (3500 m a.s.l.) The arrangement used is shown in fig. 1. The cloud chamber expanded whenever one counter at least was discharged in each of the groupsA1,A2,B1,B2, or in each of the groupsB1,B2,C1,C2, and for this two particles at least were necessary. In 12.200 minutes 801 photographs were obtained, from which we selected 120, which contain:a) groups of particles originating from a common point in the leadS, or in the three plates inside the chamber, and in which penetrating particles (recognisable for not generating secondaries in any plate) or heavy ionizing ones were present;b) showers with no evidence of penetrating particles but surely descending fromS, so that the showers appeared under 23 cm of lead (referred to as electron showers);c) some other events that were worthy to be noted. Thirty-eight photographs present showers of penetrating particles only, produced in the leadS; 9 present mixed showers and 16 electron showers. Twenty-two photographs present nuclear bursts produced in the lead plates of the cloud chamber (Tabella II). Penetrating showers observed by us are nearly all produced in the deeper region ofS. We observe moreover that the penetrating particles of a penetrating shower, which we see in the cloud chamber are normally not the same which have dischargedA1 andA2. This is in accord with the hypothesis that so-called penetrating showers are due to the more energetic bursts and contain a large number of short range particles too, in agreement with a recent suggestion ofPowell and co-workers. We have measured the scattering angles through the three plates of 38 penetrating particles associated in bursts produced inS. The scattering observed (Tabella I) is never larger than 6°, except in one case (9°), and can be explained with Coulomb scattering alone, without any anomalous scattering. The examination of the nuclear bursts produced in the plates of the cloud chamber with particular regard to those produced by ionizing particles of nuclear bursts from the leadS, lead us to a sort of cascade representation, in which the most energetic of the produced particles may successively give rise to new bursts. The mean cross section for new bursts production by ionizing particles of nuclear bursts has resulted of the order of 10−24 cm2 per nucleus. This rather strong nuclear interaction confirms that the particles produced in nuclear bursts are not generally μ-mesons but rather protons or π-mesons. More... »
