    Collisional properties of ultracold K-Rb mixtures

    Full text link
    We determine the inter-species s-wave triplet scattering length a3 for all K-Rb isotopic mixtures by measuring the cross-section for collisions between 41K and 87Rb in different temperature regimes. The positive value a3=+163(+57,-12)a0 ensures the stability of binary 41K-87Rb Bose-Einstein condensates. For the fermion-boson mixture 40K-87Rb we obtain a large and negative scattering length which implies an efficient sympathetic cooling of the fermionic species down to the degenerate regime.Comment: 4 pages, 4 figures; revised version (references added and small changes

    Проведен анализ факторов риска развития атеросклероза, дана оценка ряда теорий, объясняющих появление атеросклеротических изменений коронарных артерий. Подчеркивается роль эндотелиальной дисфункции в прогрессировании и обострении сердечно−сосудистых заболеваний. Проанализированы современные подходы к лечению атеросклероза.Risk factors of atherosclerosis development are described, a number of theories explaining atherosclerotic changes appearance in the coronary arteries are analyzed critically. The role of endothelial dysfunction in progress and exacerbation of cardiovascular diseases is emphasized. Contemporary approaches to atherosclerosis treatment are discussed

    Information on antiprotonic atoms and the nuclear periphery from the PS209 experiment

    Full text link
    In the PS209 experiments at CERN two kinds of measurements were performed: the in-beam measurement of X-rays from antiprotonic atoms and the radiochemical, off-line determination of the yield of annihilation products with mass number A_t -1 (less by 1 than the target mass). Both methods give observables which allows to study the peripheral matter density composition and distribution.Comment: LaTeX (espcrc1 style), 6 pages, 3 EPS figures, 1 table, Proceedings of the Sixth Biennal Conference on Low-Energy Antiproton Physics LEAP 2000, Venice, Ital
