- A new superdeformed band has been discovered in a EUROBALL experiment and assigned to Eu-143. It has a maximum intensity of 35% of the Eu-143 yrast superdeformed band and the transition energies of the two bands are very similar. Based on comparison with cranked shell model calculations the new band is tentatively assigned the high-N intruder configuration pi 6(2)nu 7(0) and the parity and signature quantum numbers (pi, alpha) = (-1, +1/2). In addition to the already known high-energy transition at 3361 keV another discrete line at 2715 keV was found to be in coincidence with the yrast superdeformed band. However, it was not possible to connect the decay out of either of the superdeformed bands to, known normally deformed states.

- This paper is one in a series of papers presenting a process for the removal of modified waxes from old corrugated containers by washing after alkaline hot dispersion of the recycled pulp. It presents experiments for selection of the most useful dispersants to be incorporated as wax modifiers already before the wax application. Criteria for selection were their effect on wax properties such as water and moisture resistance and their efficiency for dispersion to minimum size under hot alkaline conditions. The dispersants must also permit simple coagulation of the wax dispersion for its removal from a closed white water system. The dispersion experiments were carried out on a laboratory scale in the absence of fibers at 90°C and pH 9 to 11. Evaluated was the turbidity both at that temperature and after cooling to 20°C. For the final selection, the particle size distribution at 20°C was also measured. A few per cent of a commercial stearic acid with a minor addition of a nonionic fatty alcohol ethoxylate formula R-O-(CH2)2-O-]nH, was found to be a most suitable and economic wax additive.
