AbstractAbstract
[en] Radioisotopes have been used in two important ways in studying imperfections in alkali halide crystals. The zone refining of the compounds has been monitored by addition of tracers, and segregation coefficients have been determined from such measurements. The other application has been to insert small concentrations of impurity ions into alkali halides in order to study the phonon scattering by such impurities or by the vacancies they introduce; these measurements are carried out at very low temperatures where the phonon mean free path is limited by lattice imperfections. The most commonly used radioisotope in this work has been Ca45. This work is reviewed and some current and possible future applications of radioisotopes in this field are mentioned. (author)

Les radioisotopes ont recu deux applications importantes dans l'etude des imperfections des cristaux d'halogenures alcalins. Employes comme indicateurs, ils ont permis de controler le raffinage par zones des composes et, par suite, de determiner les coefficients de segregation. La deuxieme application a consiste a introduire dans les halogenures alcalins de faibles concentrations d'ions sous forme d'impuretes afin d'etudier la diffusion des phonons par ces impuretes ou par les lacunes que celles-ci produisent; les mesures sont effectuees a des temperatures tres basses, auxquelles le libre parcours moyen des phonons se trouve limite par les imperfections du reseau. Le radioisotope le plus frequemment employe pour ces operations a ete le 45Ca. Le memoire passe en revue ces divers travaux et signale quelques applications effectives ou possibles des radioisotopes dans le domaine considere. (author)[es]
Los autores han empleado radioisotopos en dos importantes campos del estudio de los cristales de haluros alcalinos. Uno de estos campos es el control de la purificacion por zonas de los compuestos y la determinacion de los coeficientes de segregacion por medida de las actividades de los indicadores anadidos. La segunda aplicacion consiste en introducir en los haluros alcalinos pequenas cantidades de iones-impureza a fin de poder estudiar la dispersion de fonones causada por dichas impurezas, o por los huecos que crean en la red cristalina; los autores efectuan las mediciones correspondientes a temperaturas muy bajas, ya que en tales condiciones las imperfecciones de la red imponen limitaciones al libre recorrido medio de los fonones. En estos trabajos han empleado generalmente el radioisotopo 45Ca. Los autores pasan revista a los resultados de su labor, citan algunas aplicaciones actuales de los radioisotopos en este campo y formulan observaciones sobre sus posibles aplicaciones en lo futuro.

Radioizotopy byli ispol'zovany v dvukh vazhnykh napravleniyakh dlya izucheniya defektov v shchelochnykh galoidnykh kristallakh. Zonal'noe rafinirovanie soedinenij proveryalos' izotopnymi indikatorami, a koehffitsienty izolyatsii opredelyalis' iz poluchennykh dannykh. Drugoe primenenie zaklyuchalos' v vvedenii nebol'shikh kontsentratsij primesej ionov v shchelochnye galoidy s tem, chtoby izuchit' rasseyanie fononov takimi defektami ili vakansiyami, imi vyzyvaemymi; ehti izmereniya proizvodyatsya pri ochen' nizkikh temperaturakh, pri kotorykh srednyaya velichina svobodnogo probega fonona ogranichivaetsya defektami reshetki. Radioizotopom, poluchivshim naibolee shirokoe primenenie, yavlyaetsya kal'tsij-45. (author)Original Title
