Title: New experimental approaches to investigate the fission dynamics

Abstract

The first ever achieved full identification of both fission fragments, in atomic and mass number, made it possible to define new observables sensitive to the fission dynamics along the fission path up to the scission point. Moreover, proton-induced fission of {sup 208}Pb at high energies offers optimal conditions for the investigation of dissipative, and transient effects, because of the high-excitation energy of the fissioning nuclei, its low angular momentum, and limited shape distortion by the reaction. In this work we show that the charge distribution of the final fission fragments can constrain the ground-to-saddle dynamics while the mass distribution is sensitive to the dynamics until the scission point.

  • By combining experimental and theoretical approaches, the electronic structure, molecular orientation, charge transfer dynamics and solar cell performance in donor/acceptor copolymer poly[2,7-(9,9-bis(2-ethylhexyl)-dibenzosilole)-alt-4,7-bis(thiophen-2-yl) benzo-2,1,3-thiadiazole] (PSiF-DBT) films and blended with 6,6.-phenyl-C 61-butyric acid methyl ester (PSiF-DBT:PCBM) were investigated. Good agreement between experimental and theoretical PSiF-DBT UV-Vis absorption spectrum is observed and the main molecular orbitals contributing to the spectrum were determined using DFT single point calculations. Non-coplanar configuration was determined by geometric optimization calculation in isolated PSiF-DBT pentamer and corroborated by angular variation of the sulphur 1s near-edge X-ray absorption fine structure (NEXAFS) spectra. Edge-on and plane-on molecular orientations were obtained formore » thiophene and benzothiadiazole units, respectively. A power conversion efficiency up to 1.58%, open circuit voltage of 0.51 V, short circuit current of 8.71 mA/cm{sup 2} and a fill factor of 35% was obtained using blended PSiF-DBT:PCBM as active layer in a bulk heterojunction solar cell. Ultrafast electron dynamics in the low-femtosecond regime was evaluated by resonant Auger spectroscopy using the core-hole clock methodology around sulphur 1s absorption edge. Electron delocalization times for PSiF-DBT and PSiF-DBT:PCBM polymeric films were derived for selected excitation energies corresponding to the main transitions in the sulphur 1s NEXAFS spectra. The mixture of PSiF-DBT with PCBM improves the charge transfer process involving the π* molecular orbital of the thiophene units.« less
  • A new technique is used to probe the dynamics of Penning ionization reactions involving He(2/sup 3/S) atoms and the targets K, Rb, Cs, O/sub 2/, Cl/sub 2/, and CF/sub 3/Cl. In this technique, the electrons on the 2/sup 3/S atoms are spin labeled and the polarization of the Penning electrons is determined. The data indicate that, for Rb, a significant fraction of the ionization occurs through energy transfer to a core excited state followed by autoionization. The data for the molecular targets confirm that ionization via ionic channels is important.
  • Radiocarbon has been measured in two soil profiles, one of which has been covered by a building since 1956. A comparison of the ..delta../sup 14/C values in horizons of each profile gives an estimate of the total input of atom bomb /sup 14/C into the soil profile. From the ..delta../sup 14/C and carbon density profile data, the carbon input rates, respiration rates, and diffusivity are calculated. The lack of vegetation on one soil affects the mobility and the respiration rate of the soil carbon in that soil. The data from this soil profile are also used to check the assumption,more » used in previous analyses, that there is a uniform distribution of old carbon down the soil profile. The input rate, turnover time, and diffusivity parameters determined from the ..delta../sup 14/C profiles in these soils are compared with other published data on pasture and forest soils.« less
