Summary
The total atomic cross-sections are determined in carbon, oxygen, aluminium and sulphur at photon energies 52.0, 73.0, 84.2, 145.4, 279.2 and 661.6 keV by transmission method in a good geometry set-up. The incoherent-scattering cross-sections are obtained by subtracting the theoretical sum of atomic photoeffect and coherent scattering crosssections from the measured total cross-sections. The results obtained have been compared with theoretical values.
Riassunto
Si determinano le sezioni d’urto atomiche totali per carbonio, ossigeno, alluminio e zolfo ad energie fotoniche di 52.0, 73.0, 84.2, 145.4, 279.2 e 661.6 keV con il metodo di trasmissione nell’ambito di una buona geometria. Si ottengono le sezioni d’urto di scattering incoerente sottraendo la somma teorica del fotoeffetto atomico e le sezioni d’urto di scattering coerente dalle sezioni d’urto totali misurate. Si confrontano i risultati ottenuti con i valori teorici.
