Sur les intensités absolues des rayonnements émis par 61Cu et 64Cu

Abstract: Sommaire. 2014 L'intensité des rayonnements électroniques, X et y du 64Cu et 61Cu a été étudiée à l'aide d'une chambre d'ionisation absolue et de compteurs G. M. à parois très minces. On a déterminé les rapports d'embranchement : I° des émissions 03B2-et 03B2-du 64Cu : 2,0 ± 0,15; 2° de capture K et d'émission 03B2-du 64Cu : 2,65 = 0,4 et du 61Cu : 0,55 = 0,06.On rencontre certaines difficultés dans l'interprétation théorique de ces résultats.LE JOURNAL DE PHYSIQUE ET LE RADIUM.

“…In this limit, Much effort has been devoted to IB experiments during the last thirty years. Critical reviews were compiled by Zylicz (1968) and Midgr (1972), and to a lesser extent by Bouchez and Depommier (1965), Petterson '(1965), Schopper (1966), andBer4nyi (1968). considerable progress has been achieved since, especially in the development of experimental techniques.…”

“…Some of the data on normalized IB spectra have been compiled and compared with theory by Bouchez and Depommier (1965), K&dgr et al (1970), Laneman and Lebowitz (1971a), Vanderleeden et al (1971), Kidgr (1971), Mutterer (1973c).…”

“…Wegen seiner interessanten kernphysikalischen Eigenschaften (z.B. konnte am 'Be der Kernrückstoß gemessen werden, der der Neutrinoemission folgt [31], und am 'Be ist es auch zum erstenmal gelungen, die Zerfallskonstante eines radioaktiven Elements zu beeinflussen [32][33]), und da nur 'Be zur Markierung von Beryllium geeignet ist, da es häufig als Eichnuklid in der Gammaspektroskopie verwendet wird und seine Halbwertszeit eine erneute Präparierung immer wieder notwendig macht, schien es uns wünschenswert, die Möglichkeiten zu untersuchen, 'Be durch Bestrahlen wasserstofFhaltiger Lithiumverbindungen im Kernreaktor über die Reaktionskette H(n,n')p und 'Li(p,n)'Be zu erzeugen und in trägerfreier Form radiochemisch rein abzutrennen. Zudem sind für viele Laboratorien Reaktorbestrahlungen leichter zugänglich alsCyclotronbestrahlungen.…”

“…Radioelements which have been isolated in the carrier-free state by methods involving electrodeposition reactions include (1) electronegative elements which are reduced to the metallic state by displacement with a more electropositive element or by an applied electromotive force, (#) elements which form insoluble oxides by anodic oxidation reactions, and (5) elements which form insoluble compounds with the electrode material as a result of either cathodic or anodic reactions. Carrier-free radioisotopes which have been separated by electrodeposition reactions are given in table 5. Separation of the activity from the electrode material, particularly when platinum or other noble metals are used, is usually accomplished by preferential dissolution of the radioelement.…”
