      Microscopic optical model potentials, based on density-dependent effective interactions, involve multidimensional integrals to account for the full Fermi motion of the target struck nucleon throughout the nucleus. If a ...
    • Vega, Andrés; Ramírez Rodríguez, Oney; Martínez Cifuentes, Maximiliano; Ibáñez, Andrés; Araya Maturana, Ramiro (WILEY-BLACKWELL PUBLISHING, INC, 2009-02)
      The title molecule, C14H14O3, contains two fused six-membered carbon rings with keto groups at positions 1, 4 and 5 and a gem-diethyl group at position 8. The molecule is close to planar (maximum deviation = 0.044 angstrom), ...
    • Casassus Montero, Simón; Roche, P. F.; Aitken, D. K.; Smith, C. H. (BLACKWELL SCIENCE LTD, 2001-11-01)
      A sample of 25 infrared-bright planetary nebulae (PNe) towards the Galactic bulge is analysed through 8-13 mum spectroscopy. The classification of the warm dust emission features provides a measure of the C/O chemical ...
