The Continuous Gamma-Ray Spectrum Accompanying Beta-Decay

Abstract: The spectral distribution and absolute intensity of the internal bremsstrahlung emitted in beta-decay was investigated in P 32 , Y 91 , and RaE. The gamma-radiation was detected by means of a Nal(Tl) crystal, phototube, linear amplifier and one-channel discriminator. Care was taken to avoid spurious effects, and corrections were made for several factors. Both the spectral distributions and the absolute intensities of the continua are in excellent agreement with theoretical predictions. The differences in the s… Show more

“…1(a). In the case of Fe 55 , the decay energy is known accurately from several measurements of the inner bremsstrahlung end point, 10 and these results agree well with (p,n) threshold measurements. 11 The latter value (232db2 keV) was used in our calculations.…”

“…J. Chem. Downloaded from www.nrcresearchpress.com by 34 conversion electrons, inner bremsstrahlung, and inner bremsstrahluilg electrons (7,9,10,35,43,49). Similarly bremsstrahlung production (3, 49) and secondary electron production (32,33,36) in the very thin film can be shown to be several orders of magnitude too low.…”

“…-Toute désintégration par émission (3 ou par capture d'électron est accompagnée par un spectre X continu, dit « spectre de freinage interne ». Ce phénomène a été étudié expérimentalement par divers auteurs pour des transitions p pur tel que les 32P [1], [2], [7], [8], [9], "UX2 [5], [6], le RaE [3], [4], [7], [8], et le 91Y [8]. Diverses techniques ont été utilisées : méthode d'absorption avec comme détecteur une chambre d'ionisation ou un compteur Geiger-Müller [1] à [6]; technique utilisant le compteur à scintillations qui permet d'obtenir directement le spectre [7], [8]; le compteur proportionnel utilisé par Renard pour l'étude de la partie de basse énergie du spectre [9].…”

“…Ces résultats sont analogues à ceux trouvés d'une part par Novey [ [8]. Comme ces derniers auteurs [8], nous constatons un excès d'impulsions par rapport aux prévisions de la théorie, pour les énergies comprises entre 0,1 et o,5 mC2.…”
