Fluctuations of Track Parameters in Nuclear Emulsions

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The fluctuations in nuclear-emulsion track parameters have been studied in a G5 emulsion of low minimum grain density by measurements of the blob density and integral gap length of long tracks of relativistic heavy nuclei. The intrinsic variations arising from the statistical nature of the process of track formation were found to be in good agreement with those predicted by the Blatt fluctuation theory. Subjective, emulsion and other variations were found in some cases to be comparable to the intrinsic variations. A method of estimating these fluctuation effects in any general experimental measurement is given. Nuclear Research Foundation within the University of Sydney.

Riassunto

In una emulsione G5 di bassa densità minima di granuli si sono studiate le fluttuazioni dei parametri di traccia per mezzo di misure di densità dei blob e della intera lunghezza di gap di lunghe tracce di nuclei pesanti relativistici. Le variazioni intrinseche derivanti dalla natura statistica del processo di formazione della traccia furono trovate in buon accordo con quelle predette dalla teoria delle fluttuazioni di Blatt. Variazioni soggettive inerenti all’emulsione ed altre variazioni furono in alcuni casi trovate confrontabili alle variazioni intrinseche. Si dà un metodo per la valutazione di questi effetti di fluttuazione in qualsiasi serie di misure sperimentali.
