An International Summer School on selected topics in nuclear physics is organized b y the Nuclear Research Institute of the Czechoslovak Academy of Sciences under the co-sponsorship of the International Atomic Energy Agency. The summer school will be held in the Low Tatra Mountains, from 20th August to 8th September 1962. The following courses of lectures will be held: 1) N. Austern, Recent developments in nuclear reaction theory; 2) S. T. Belyayev, Nucleon pairing correlations and collective excitations of nuclei; 3) N. N. Bogolyubov, General topics in the many particle problem; 4) J. P. Elliott, The nuclear shell model and its relation with other nuclear models; 5) I. S. Shapiro, Dispersion theory of direct nuclear reactions; 6) V. G. Solovyov, The superconductive properties of atomic nuclei; 7) H. A. Tolhoek, Theory of weak interactions amongst nucleons and leptons; 8) Gamma properties of atomic nuclei (lecturer and exact title not yet specified). Further information can be obtained from Prof. V. Votruba, Nuclear Research Institute, l~e~, Czechoslovakia.
NEUTRON

PHYSICS
The Institute of Physics and The Physical Society announces t h a t it is arranging a three day course on the theory and practice of thermal neutron scattering diffraction, as applied to the study of solids and liquids, to be held in Imperial College, London, from September 25th-27th, 1962. I t will be followed b y a one-day conference on current neutron work on September 28th. The course is designed to make available to physicists a coherent account of the uses of thermal neutrons in the study of solids. It is expected t h a t the lectures will cover the following topics: (1) Elastic scattering and structure determination; magnetic structures and hydrogen bonds. (2) Inelastic scattering from systems containing moving nuclei; phonon and spin wave scattering. (3) Scattering from fluctuating systems; liquids, magnetic critical scattering. (4) Scattering from disordered solid solutions; magnetic form factors. (5) Crystal defect scattering. (6) The experimental techniques peculiar to these fields. Both the course and the conference will be non-residential and those wishing to attend are strongly advised to reserve accommodation in London as soon as possible. Further details will be available in April from the Administration Assistant, The Institute of Physics and The Physical Society, 47 Belgrave Square, London, S.W.I.
