Elastic photon-deuteron scattering and the nucleon polarizability

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

An analysis of the existing experimental data on the elastic scattering of photons by deuterons, is carried out in the framework of the impulse approximation. Nevertheless, it also attempts to take into account certain effects which are not given by the impulse approximation. Including these effects, we have been able to improve the prediction of the theory on the deuteron Compton effect. Based on this analysis we make an estimation of the neutron electric polarizability. We found it ∼1.2·10−42 cm3. In addition we discuss experiments in proton, deuteron and4He Compton effect with polarized γ’s, for a better specification of the polarizabilities of the proton and neutron as well.

Riassunto

Si esegue una analisi dei dati sperimentali esistenti sulla diffusione elastica di fotoni su deutoni nell’ambito dell’approssimazione dell’impulso. Nondimeno, si tenta di tener conto di taluni effetti che non sono presi in considerazione nell’approssimazione dell’impulso. Includendo questi effetti si riesce a migliorare le predizioni della teoria sull’effetto Compton su deuterio. Basandosi su questa analisi si dà una stima della polarizzabilità elettrica del neutrone. Si è ottenuto un valore di ∼1.2·10−42 cm3. In aggiunta si discutono esperimenti di effetto Compton su protone, deuterio ed4He con γ polarizzati, per una migliore determinazione della polarizzabilità tanto del protone che del neutrone.

  33. It is interesting to notice that with the help of polarized γ’s obtained by using crystals (31), we also simplify the experimental procedure in the case of Compton scattering. This is because the bremsstrahlung spectrum in crystals gives a peak at a certain energy value, which we may exploit; consequently we arrange our apparatus in such a way that, although we remain with a reasonable count rate, we may reduce considerably (sometimes ∼100 times) the contamination of our data from the γ’s coming from the π0 which are photoproduced at the same time (32).
