Search for γ radiation from the cygnus a radiosource

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

An experiment is described attempting to detect energetic γ-radiation from a peculiar celestial object (Cygnus A) interpreted by some authors as a collision between a galaxy of matter ond one of anti-matter. The experiment was negative and settled as upper limit for the γ-flux a value of about 5·10−3 quanta/cm2 s, which is about two orders of magnitude smaller than estimated by Morrison under the assuption previously mentioned.

Riassunto

Si descrive un esperimento con il quale è stato tentato di mettere in evidenza radiazione γ energica proveniente da un particolare oggetto celeste (Cigno A) supposto da alcuni autori essere una collisione tra una galassia di materia ed una di antimateria. L’esperimento ha dato risultato negativo, ed ha permesso di stabilire per il flusso γ un limite superiore di circa 5·10−3 quanti/cm2 s, valore di circa due ordini di grandezza inferiore a quello stimato da Morrison nell’ipotesi precedentemente menzionata.
