[en] The authors continue the literature scan on A = 21-44 nuclei. Data is presented of gamma-ray strengths for the A = 6-20, 21-44 and 45-90 regions. (G.T.H.)

[en] In the past year the transient magnetic field has been investigated for light ions in ferromagnetic Gd in continuation of measurements reported previously. Attention has also been paid to a comparison of the transient fields for ²⁸Si in various ferromagnetic materials to check whether or not the field strengths scale with the density of polarized electrons in the host. Finally, g-factors of short-lived excited states of ³¹P have been measured. For this purpose the accurately calibrated transient field in Fe has been used. (Auth.)

[en] A set of γ-ray energies in the range 0.06 - 3.50 MeV, all with uncertainties of at most 10 ppm, is available for the energy calibration of γ-ray spectra. In order to extend this energy range, the energy of the 6.13 MeV transition in ¹⁶O has been measured in terms of the gold-standard (¹⁹⁸Au, 411804.4 +- 1.1 eV). (Auth.)

[en] Monoenergetic γ-rays of variable energy, provided by (p,γ) reactions on light nuclei, have been used in nuclear photoexcitation experiments of both unbound and bound nuclear levels. The reactions ¹¹B(γγ)¹¹B, ²⁸Si(γ,γ)²⁸Si, ²³Na(γ,γ)²³Na and ²⁰⁸Pb(γ,γ)²⁰⁸Pb are discussed. (Auth.)

[en] A Compton-suppression spectrometer and three conventional Ge(Li) detectors of 80, 95 and 100 cm³ have been used in observing the reactions: ²²Ne(p,γ)²³Na, ³⁶S(p,γ)³⁷Cl, and ⁵⁴Fe(p,γ)⁵⁵Co. (Auth.)

[en] In the past year the Monte Carlo design calculations for a Compton-suppression spectrometer (CSS) with large solid angle have been completed. The present CSS with the small solid angle of 7.5 msr is very suitable for the measurement of singles spectra and angular distributions, because in such one-detector experiments the (advantageously) small solid angle can be compensated for by the use of a higher beam intensity. Properties of yrast levels in ³⁴Cl, ⁴⁴Ca and ⁵⁹Ni have been investigated. High-spin levels of these nuclei are populated in the reactions ²⁴Mg(¹²C,pnγ)³⁴Cl, ²⁸Si(¹⁸O,2pγ)⁴⁴Ca and ⁴⁶Ti(¹⁶O,2pnγ) ⁵⁹Ni at bombarding energies of 30-45 MeV. Some results specific for ³⁴Cl are discussed. (Auth.)

[en] The authors report on two different subjects which have in common that they involve recoil-distance measurements with plunger systems. The first subject is classical, it deals with a time-dependent deorientation g-factor and a life-time measurement, partly reported on previously. The second subject deals with an attempt to measure nuclear spin deorientation in a free ion that has passed through a thin magnetized Fe foil. In this case part of the ions are expected to be polarized which should lead to a spin precession superimposed on a random deorientation. (Auth.)

[en] Gamma-gamma angular correlations have been measured in the ²³Na(n,γ)²⁴Na reaction. These data have been analysed in conjunction with the results of previous measurements of the circular polarization of γ-rays produced upon capture of polarized neutrons. This work has provided the γ-ray mixing ratios of 17 transitions and the channel spin mixing parameter α of 7 primary transitions. (Auth.)

[en] A continuation of the theoretical investigation of medium-heavy nuclei turns out to be quite rewarding because (i) the nuclei not too far from the doubly-magic ⁵⁶₂₈Ni₂₈ core can be treated quite well with the shell model and (ii) these nuclei exhibit some interesting collective properties. This makes a further study feasible of the relation between microscopic and collective properties. (Auth.)
