    Notes: Abstract The12C(6Li,d)16O reaction at 28 MeV and 34 MeV bombarding energy are analized in Zero Range Distorted Wave Born Approximation (ZR-DWBA) utilizing microscopic four-particle transfer form factors. Configuration mixing is taken into account utilizing the Zuker, Buck and McGrory wave functions for16O. Good agreement is found for the angular distributions. For the relative cross sections to the different excited states, acceptable agreement is found for the 1− state (7.12 MeV) and 4+ (10.56 MeV), while the model clearly underestimates the transition to the 2+ state (6.92 MeV).

    Notes: In the framework of the SCF-RPA scheme and ppp approximation we studied the excitation spectrum of pyrene, coronene, ovalene, and hexabenzocoronene. The triplet stability matrix of the corresponding Hartree-Fock solution was also studied for each molecule. At variance with the case of long linear polyacenes [M. Baldo, G. Piccitto, R. Pucci, and P. Tomasello, Phys. Lett. 95A, 201 (1983)], all these molecules do not display Hartree-Fock triplet instability. Furthermore, the theoretical analysis indicates that the electronic structure of the molecular series can be characterized by a dimensionality intermediate between one and two, with a smooth transition between the two limits. The transition is essentially determined by the molecular shape. The analysis is supported by the fairly good agreement of the theoretical spectra with the available experimental data.
