Новое зкспериментальное подтверждение для ядра8Не
In this work we present the analysis and interpretation of an event, consistent with the production and subsequent decay of the exotic nucleus8He, found in the study of K− interactions with nuclear-emulsion nuclei at different energies.
Análisis crítico de la introducción de la física moderna en la enseñanza media
SUMMARY: This paper deals witb tbe introduction of Modern Pbysics in bigb scbool curricula, trying to answer to tbese questions: - How are Modern Pbysics concepts introduced? -Do pupils get a correct understanding of tbese concepts? Some results are given wbicb sbow tbe need of a deep cbange in tbe way Modern Pbysics concepts are usualy taugbt.
Measurement of the Lifetime of Neutral Charmed Mesons
Abstract The lifetime of neutral charmed particles photoproduced in emulsion has been measured. The lifetime value presented here was obtained from a sample of 22D 0 mesons, 18 of which have their charmed partner seen in emulsion. The sample is essentially background-free. The result obtained is τ D 0 =(2.11 +1.21 -0.63 )×10 13 s The D 0 mass derived from 8 3C events is m D 0 = 1856 ± 36 MeV/ c 2 .
Short and medium effects on the environment of Valencia, Spain, of the Chernobyl nuclear plant accident.
As a consequence of the 26 April 1986 accident at the Chernobyl nuclear plant, a large amount of radioactivity was released into the atmosphere. The radioactive plume formed could be detected in practically the whole of the Northern Hemisphere a few days later. The zone most affected by the radioactive cloud over Spain was that of the Mediterranean coast and the Balearic Islands. In this paper, the authors examine the level of the radioactive contamination reached in various receptive media in Valencia, such as air, dry-fallout, water, soil, grass and milk samples collected in Valencia immediately after the accident. The activity levels are compared with those found during 1964 and 1965 due…
