    Description / Table of Contents: Riassunto Si è studiata la termoluminescenza dell'α-alumina registrando l'emissione di luce in funzione, simultaneamente, della temperatura e della lunghezza d'onda. Partendo da allumina amorfa, i campioni sono stati preparati mediante trattamenti termici nell'intervallo di temperatura da 850 a 1400°C. La luce registrata mostra due bande spettrali a 553 e 706 nm, emesse a temperature vicine a 500 K. Queste bande riappaiono nella regione attorno a 700 K con intensità ridotta. La banda a 553 nm svanisce nei campioni trattati a temperature al di sopra di 1200°C. I risultati sono paragonati ad un modello cinetico che spiega gli aspetti sperimentali più significativi. Vengono proposti alcuni argomenti qualitativi che potrebbero essere utili per identificare la natura dei difetti reticolari responsabili dell'emissione termoluminescente osservata.
    Abstract: Резюме Исследуется термолюминесценция α-корунда, регистрируя интенсивность светового излучения в зависимости от температуры и длины волны. Образды изготавливаются из аморфного корунда, используя термическую обработку в области температур от 850°C до 1400°C. Термолюминесценция обнаруживает две спектральных зоны 553 и 606 нм, излучаемые при температурах, близких к 500 K, которые снова появляются в области 700 K с уменьшенной интенсивностью. Зона 553 нм затухает в образцах, обработанных при температуре выше 1200°C. Этот результат сравнивается с кинетической моделью, которая объясняет наиболее сушественные экспериментальные особенности. Приводятся некоторые качественные аргументы, которые могут быть полезны для идентификации природы дефектов решетки, ответственных за наблюдаемое термолюминесцентное излучение.
    Notes: Summary The thermoluminescence of α-alumina was investigated by recording light emission simultaneouslyvs. temperature and wavelength. Samples were prepared, starting from amorphous alumina, by means of thermal treatments in the 850 to 1400°C temperature range. The recorded light exhibits two spectral bands at 553 and 706 nm emitted at temperatures close to 500 K, which reappear in the 700 K region with reduced intensity. The 553 nm band fades away in samples treated at temperatures exceeding 1200°C. The results are compared to a kinetic model which explains the most significant experimental features. Some qualitative arguments are advanced which could be useful in identifying the nature of the lattice defects responsible for the thermoluminescent emission observed.

    Notes: Summary Two double-layered perowskitic compounds have been investigated by XRD analysis and Mössbauer spectroscopy. The experimental data allow the conclusion that magnetization is almost parallel to the stacking planes of these layered structures.

    Description / Table of Contents: Riassunto Si discute un metodo per adattare funzioni a curve sperimentali in casi in cui si possa omettere un fattore di scala sull'asse delle ordinate. Esso consiste nel rendere massimo il coefficiente di correlazione tra la curva e la funzione. Si deduce una relazione tra il chiquadro e il coefficiente di correlazione che dimostra l'equivalenza tra i metodi dei minimi quadrati e della correlazione. Questa relazione, inoltre, permette di utilizzare la prova di affidabilità del chi-quadro quando si è determinato il coefficiente di correlazione. Si presenta come esempio, un'applicazione alla spettroscopia Mössbauer.
    Abstract: Резюме Обсуждается метод подгонки экспериментальных кривых в случаях, когда масштабный множитель по вертикальной оси может быть опущен. Предложенный метод заключается в максимизации коэффициента корреляции между кривой и подгоночной функцией. Получается соотношение между χ2 и коэффициентом корелляции, которое обнаруживает эквивалентность между методом наименьших квадратов и методом корреляций. Это соотношение позволяет нам использовать проверку надежности χ2, когда получен коэффициент корреляции. Предлагается иллюстративный пример применения предложенного подхода к Мессбауэровской спектроскопии.
    Notes: Summary A method is discussed for the fitting of experimental curves in cases in which a scale factor on the vertical axis can be omitted. It consists of maximizing the correlation coefficient between curve and fitting function. A relationship between chi-square and correlation coefficient is obtained, which shows the equivalence between least square and correlation methods. This relationship, moreover, allows us to utilize the chi-square reliability test when the correlation coefficient is found. An exemplifying application to Mössbauer spectroscopy is presented.
