    Notes: Abstract: Collinear laser spectroscopy experiments in the LuI transition 5d6s2 2D3/2→ 5d6s6p 2D3/2 were performed on all lutetium isotopes in the range of 161-179Lu. The nuclear spins, magnetic moments and quadrupole moments were determined from the hyperfine structures observed for 19 ground states and 11 isomers. Variations in the mean square charge radii as a function of neutron number were obtained from the isotope shifts. These data considerably extend the systematics of the properties of nuclei in the upper rare-earth region. A particular feature is the appearance of high-spin and low-spin ground states and isomeric states in the vicinity of the stable 175Lu, partly arising from aligned neutron pairs. The results clearly show that the deformation properties are nearly independent of the occupancy and the coupling of single-particle states. Theoretical predictions of deformation are confirmed in a consistent description of the measured radii and quadrupole moments. For all observed states, the spins and magnetic moments allow the assignment of rather pure Nilsson configurations.

    Description / Table of Contents: Summary This report documents a case of ball variance in a Smeloff-Cutter aortic prosthesis occurring 24 years after implantation. After episodes of embolic complications the patient died in acute shock. The silicone rubber ball showed several alterations including discoloration, grooving, cracking, swelling and subtotal fracture of the poppet. Terminal valvular malfunction was caused by complete thrombosis of the prosthesis. In most patients ball variance occurred during the first years after valve replacement; thus, the observed case is a very rare late complication of a ball-valve prosthesis.
    Notes: Zusammenfassung Berichtet wird über einen Fall von Ballvarianz einer Smeloff-Cutter-Prothese in Aortenposition 24 Jahre nach Implantation. Nach vorausgegangenen embolischen Komplikationen verstarb der Patient im kardiogenen Schock. Der Silikon-Kautschuk-Ball der Prothese zeigte eine ausgeprägte Degeneration mit gelblicher Verfärbung, Rillen- und Rißbildung bei Schwellung und subtotaler Fraktur. Daraus resultierte eine terminale Prothesenfunktionsstörung mit kompletter Thrombose der Klappe. Ballvarianz als Komplikation trat bei der großen Mehrzahl der Patienten während der ersten Jahre nach Implantation auf; somit ist die beobachtete Komplikation ein sehr seltenes Ereignis nach Implantation einer Kugel-Käfig-Prothese.
