Studies of anomalous scattering of neutrons from CdI2 single crystals were continued over an energy range including the cadmium resonance peak at 0.178 eV. The complete (h 0 l) zone of reflections was measured at one wavelength (1.075 A) in order to permit a structure refinement which would simultaneously give a precise measurement of the complex scattering amplitude of cadmium at this wavelength. Selected reflections were also measured at several other wavelengths. In addition, a single crystal of 113CdI2 was grown, and Bragg intensities were measured for several reflections at 1.075 A. A complete least-squares refinement of the (h 0 l) zone was computed which included anisotropic thermal parameters as well as the complex scattering amplitude of cadmium. The latter is in remarkably good agreement with that calculated with the aid of the Breit-Wigner single level formulation using the neutron and gamma widths determined for cadmium by Brockhouse.

On donne ici la relation qui lie les energies diffractees par un reseau echelette dans les differents ordres, pour deux directions perpendiculaires du champ electrique de l'onde incidente. Les equations du probleme general sont obtenues en ecrivant les conditions que doivent satisfaire les ondes sur la surface du reseau. L'application est faite pour un cas bien determine ; l'accord avec l'experience est assez satisfaisant.

The 0/sup +/ levels in /sup 16/O are studied in terms of the shell model with zero-range nuclear forces. All the 0/sup +/ levels are described as a mixture of the closed shell configuration and configurations with 2h omega unperturbed energies. The spurious states are eliminated, and the energy matrix is diagonalized. The interference between the ground state and the first excited state correctly explains the monopole matrix element and the ratio of the transition probabilities from the first 1-T = 1 level to these two levels. For the excitation energies, the agreement is not very good. (auth)
根据零距离核力的壳层模型，研究了/sup 16/O中的0/sup +/能级。所有的0/sup +/能级都被描述为闭合壳层构型和具有2h无扰动能量的构型的混合物。消除了伪态，对能量矩阵进行了对角化处理。基态和第一激发态之间的干涉正确地解释了单极矩阵元素和从第一个1- t = 1能级到这两个能级的跃迁概率之比。激发态能的一致性不是很好。(认证)
