een proposed as possible interstellar molecule, whereas the corresponding gas phase far infrared are not wellexplored. We carry out this work in collaboration with the University of Huelva and the University of Lille.Finally, the collisional study of SO 2 with ortho-H 2 and para-H 2 has been completed at very low temperatures.Determination of the collisional parameters for abundant species in astrophysical sources and molecular hydrogen isessential to understand the observed intensities. These depend on the populations of the levels, which are the resultof radiative and collisional excitations and de-excitations. We are studying sulphur oxides and carbon-chains. Theparameters are obtained in molecular dynamics calculations using as input, Van der Walls potential energy surfaces.These are determined with very accurate ab initio calculations. The theoretical study of SO 2 has allowed to predicttransitions and a new maser motivating new astrophysical observations that have demonstrated the accuracy of thetheoretical predictions.2B.2 NUCLEAR, VIBRATIONAL AND DISORDERED MEDIASPECTROSCOPY DEPARTMENTRESEARCH LINES:‣ Experimental Nuclear Physics.‣ Study of excited states and nuclear resonances.‣ Nuclear structure studied in reactions with stable and exotic nuclei at low, medium and relativisticenergies.‣ Computing simulations using R3BRoot for nuclear physics experiments.‣ Systems devoid of long-range order.‣ Advanced instrumentation.‣ Surface Spectroscopies.‣ Surface Plasmon Photonics and metamaterials.‣ Biospectroscopy.‣ Chemical-Physics of deposition and ablation processes.RESEARCH SUBLINES:Experimental studies of light nuclei close to and beyond the driplines.Beta decay studies of drip line nuclei.R&D for FAIR (Facility for Antiprotons and Ion Research).Study of the nuclear break up mechanism by multiparticle detection.Study of the structure and dynamics of halo nuclei.Direct nuclear reactions.Magnetic moment measurements in exotic nuclei using radioactive ion beams.Nuclear instrumentation.Computing tools in Experimental Nuclear (R3BRoot).Data analysis tools.Nuclear Physics experiments for FAIR.Nuclear structure physical behaviour at nano-scales.Microscopic structure and dynamic of disordered condensed matter.Advanced instrumentation development for neutron sources.Laser Induced Breakdown Spectroscopy (LIBS).Surface-enhanced (SEVS) on metal nanostructures.Vibrational Spectroscopy applied to Cultural Heritage.SEVS applied to pollutant detection.Applications of SERS to biology: drug/biomolecule interaction.Plasmon resonances on metal nanostructures (Nanoantennae): Raman and Fluorescence.Metamaterials in the optical range.Infrared Laser induced ablation plasmas.Laser Induced Breakdown Spectroscopy (LIBS).EMPLOYED TECHNIQUES:oBeta decay studies at ISOL facilities, ISOLDE and REX-ISOLDE@CERN.54
