“…where A kk are the angular correlation coefficients related to the properties of the transitions, P k are the Legendre Polynomials of the k th order, Q kk are coefficientes related to finite solid angle corrections (see [2,3]) and α is a normalization constant. The A kk coefficients can be split in two separate coefficients, each related to one of the transitions involved:…”

Abstract. In this work an approach is proposed to the analysis of directional angular correlation data in which the function W(θ) used to fit the experimental data already includes the relations between the A kk parameters and the mixing ratios (δ), so that the angular correlation function is fitted explicitly in terms of the mixing ratio of the transition of interest; the normalization factor that arises from the fit can also be used, under certain situations, to determine the intensity of one of the transitions. In order to verify the usability and consistence of this method, some well-determined cascades from 152 Eu and 60 Co standard sources, as well as from the β − decay of 193 Os, were analyzed, and the results compared to the literature values, allowing for a discussion of the performance of this approach.

“…However, owing to the statistical nature of the photon energyloss process, Monte Carlo calculations are required to obtain accurate values for the Q, coefficients. Results of these calculations for detectors of different sizes and for different source-to-detector distances can be found in the literature [7,8]. Although these are usually given to four significant figures, it should be remembered that the calculations were done assuming ideal experimental conditions, i.e., uniformity of detector efficiency and exact detector-to-source distances.…”

temperature nuclear orientation thermometry, in particular y-ray anisotrwpy therimometry, is discussed both from a theoretical and practical point of view. Detailed information is given on the most often used 7-ray anisotropy TMermnometers, along with a comprehensive descriptiom of the --ray anisotropy technique. The "Co in (hcp) cobalt single crystal F-ray anisotropy thermometer is discussed in considerable detail since it is used more frequently in comparison experiments with other primary thermomreters. Recent experimental results using --ray amisotropy thermometers are also reviewed.

Gamma-ray intensity measurements in 160Dy have been carried out using a Ge(Li) detector. In addition, 1'-1' angular correlation measurements have been made on 10 cascades in 160Dy using a Ge(Li)-NaI(TI) fast coincidence arrangement. These cascades are 299 ..... 966, 299 ..... 879, 879 ..... 87, 197 ..... 87, 962 ..... 87, 21S ..... 962, 299 ..... (879) ..... 87, 299 ..... (682) ..... 197, 21S ..... (962) ..... 87 and 21S ..... (76S) ..... 197 keY. Of these, the 21S ..... (962) ..... 87 and 21S ..... (76S) ..... 197 keY cascades have been measured for the first time. The multipolarities of the 197, 21S, 299, 879 and 962 keY transitions were found to be E2+(0'2�0'2)%M3, El +(2'S~~:g)%M2, El +(2~~)%M2, Ml +(99�1)%E2 and Ml + (98 � 1) % E2 respectively.
