Structural and magnetic investigation of Fe3+ and Mg2+ substitution into the trigonal bipyramidal site of InGaCuO4

Creator:: Grajczyk, Rosa, Berthelot, Romain, Muir, Sean, Sleight, A. W., and Subramanian, M. A.
Abstract:: The solid solutions of InGa₁₋ₓFeₓCuO₄, InFeCu₁₋ₓMgₓO₄, and InGa₁₋ₓFeₓCu₁₋ₓMgₓO₄ were synthesized and characterized through the use of X – ray and neutron diffraction, and DC – magnetism measurements. All compositions of InGa₁₋ₓFeₓCuO₄ are single phase and crystallize in the R3m space group, but a transformation to the spinel InFeMgO₄ structure was...

Probing structural evolution along multidimensional reaction coordinates with femtosecond stimulated Raman spectroscopy

Creator:: Frontiera, Renee R., Fang, Chong, Dasgupta, Jyotishman, and Mathies, Richard A.
Abstract:: Mapping out multidimensional potential energy surfaces has been a goal of physical chemistry for decades in the quest to both predict and control chemical reactivity. Recently a new spectroscopic approach called Femtosecond Stimulated Raman Spectroscopy or FSRS was introduced that can structurally interrogate multiple dimensions of a reactive potential energy...

Stability of the ferromagnetic ground state of La₂ MnNiO₆ against large compressive stress

Creator:: Haskel, D., Fabbris, G., Souza-Neto, N. M., van Veenendaal, M., Shen, G., Smith, A. E., and Subramanian, M. A.
Abstract:: The effect of quasi-hydrostatic pressure upon the ferromagnetic ground state of magnetodielectric, double- perovskite La₂ MnNiO₆ is investigated using x-ray absorption spectroscopy and diffraction measurements in a diamond anvil cell. The Mn-O-Ni superexchange interaction that gives rise to ferromagnetism in this cation- ordered structure is stable to at least 38...

Search for inverse fission of uranium

Creator:: Yanez, R., Loveland, W., Beckerman, J., Leonard, M., Gross, C. J., Shapira, D., Liang, J. F., Kohley, Z., and Varner, R. L.
Abstract:: Background: There is a long-term interest in running the fission reaction backward, i.e., studying the "inverse fission" of uranium. The recent availability of beams of n-rich fission fragments has stimulated interest in this endeavor. Purpose: To search for inverse fission in the reactions Sn-¹²⁴,Sn-¹3² + Mo-¹⁰⁰. Method: In the Sn-¹²⁴...

Effects of molecular potential and geometry on atomic core-level photoemission over an extended energy range: The case study of the CO molecule

Creator:: Kukk, E., Travnikova, O., Mondal, S., Kimura, M., Sakai, K., Miron, C., Martín, F., Ueda, K., Ayuso, D., Thomas, T. D., Decleva, P., Patanen, M., Argenti, L., Plésiat, E., Palacios, A., and Kooser, K.
Abstract:: We report an experimental and theoretical study of single-molecule inner-shell photoemission measured over an extended range of photon energies. The vibrational intensity ratios I (nu = 1)/I (nu = 0) from the C 1s photoelectron spectra of carbon monoxide, although mostly determined by the bond length change upon ionization, are...

Fusion of Sn-124,Sn-132 with Ca-40,Ca-48

Creator:: Kolata, J. J., Roberts, A., Howard, A. M., Shapira, D., Liang, J. F., Gross, C. J., Varner, R. L., Kohley, Z., Villano, A. N., Amro, H., Loveland, W., and Chavez, E.
Abstract:: Fusion excitation functions for the reactions of Sn-¹²⁴,Sn-¹³² with Ca-⁴⁰,Ca-⁴⁸ were measured at energies near and below the Coulomb barrier. Weak sub-barrier fusion enhancement accounted for by coupling to the first 2(+) and 3(-) states in the target and projectile was observed for Sn-¹²⁴,Sn-¹³² + Ca-⁴⁸. However, the Sn-¹²⁴,Sn-¹³² +...

Nonstoichiometric Intensities in Core Photoelectron Spectroscopy

Creator:: Söderstrom, J., Mårtensson, N., Travnikova, O., Patanen, M., Miron, C., Sæthre, L. J., Børve, K. J., Rehr, J. J., Kas, J. J., Vila, F. D., Thomas, T. D., and Svensson, S.
Abstract:: X-ray photoemission spectroscopy is used in a great variety of research fields; one observable is the sample's stoichiometry. The stoichiometry can be deduced based on the expectation that the ionization cross sections for innershell orbitals are independent of the molecular composition. Here we used chlorine-substituted ethanes in the gas phase...

Measurement of the fusion probability, P[subscript CN], for hot fusion reactions

Creator:: Yanez, R., Loveland, W., Barrett, J. S., Yao, L., Back, B. B., Zhu, S., and Khoo, T. L.
Abstract:: Abstract: Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, P[subscript CN], i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and...

A comprehensive comparison of transition-metal and actinyl polyoxometalates

Creator:: Nyman, May and Burns, Peter C.
Abstract:: While the d⁰ transition-metal POMs of Group V (V⁵⁺, Nb⁵⁺, Ta⁵⁺) and Group VI (Mo⁶⁺, W⁶⁺) have been known for more than a century, the actinyl peroxide POMs, specifically those built of uranyl triperoxide or uranyl dihydroxidediperoxide polyhedra, were only realized within the last decade. While virtually every metal on...
