Emission multiple de fragments de charge supérieure ou égale a 3 lors des désintegrations des noyaux lourds de l'émulsion ionographique

Summary

We have studied the fragment emission in nuclear emulsions for incident-proton energy of 25 GeV and also looked for double and multiple fragment emission for charges ≥3. To discriminate the simple fragments, we have applied a photometrical method and have observed at least 250 stars which emit two or more fragments of charges ≥3. An analysis of the results indicates a good agreement with the Russian results and it seems that, for fragments of energy lower than 4.5 MeV per nucleon, the emissions of the two fragments would be interdependent.

Riassunto

Si è studiata l'emissione di frammenti nelle emulsioni nucleari per un'energia dei protoni incidenti di 25 GeV e si è ricercata l'emissione di frammenti doppi o multipli per cariche ≥3. Per discriminare i frammenti semplici si è applicato un metodo fotometrico e si sono osservate almeno 250 stelle che emettono due o più frammenti con cariche ≥3. Un'analisi dei risultati indica un buon accordo con i risultati dei russi e sembra che, per frammenti di energia inferiore a 4.5 MeV per nucleone, le emissioni dei due frammenti sono interdipendenti.
