The absorption mean free path L of star-producing radiation was determined by means of the local production of neutrons in condensed materials; for that purpose a neutron monitor was installed in an aircraft, and two flights were performed at the geomagnetic latitudes 23.3°S (Buenos Aires, República Argentina) and 15°S (Asunción, República del Paraguay). The results show an increase in L of about 20% for an altitude increase of 6000 m in Buenos Aires, and of 40% in Asunción, for the same altitude increase; the total L value in Asunción was found to be 175 g cm-2, while in Buenos Aires it was 163 g cm-2, that is, approximately 8% lower. © 1961 The American Physical Society.
