• Localização das interações em espalhamento nuclear a energias médias 

      Steffani, Maria Helena (1979) [Dissertação]
      Estuda-se a densidade de probabilidade, no espaço de configuração, de núcleons de energia no intervalo de 80 a 320 MeV, espalhados por potenciais óticos complexos centrais de formas arbitrárias que simulam a interação ...
    • Novas fases amorfas de carbono produzidas por irradiação iônica de filmes de C/sub 60/, [alfa]-C e [alfa]-C:H 

      Baptista, Daniel Lorscheitter (2003) [Tese]
      Neste trabalho estuda-se a formação de novas fases de carbono amorfo através da irradiação iônica de filmes de fulereno, a-C e a-C:H polimérico. Os efeitos da irradiação iônica na modificação das propriedades ópticas e ...
    • Probing the symmetry energy from the nuclear isoscaling 

      Souza, Sergio Ricardo de Azevedo; Tsang, M. B.; Donangelo, Raul José; Lynch, William G.; Steiner, Andrew W. (2008) [Artigo de periódico]
      Using different parametrizations of the nuclear mass formula, we study the sensitivity of the isoscaling parameters to the mass formula employed in grand-canonical calculations. Previous works on isoscaling have suggested ...
    • Statistical multifragmentation model with Skyrme effective interactions 

      Souza, Sergio Ricardo de Azevedo; Carlson, Brett Vern; Donangelo, Raul José; Lynch, William G.; Steiner, Andrew W.; Tsang, M. B. (2009) [Artigo de periódico]
      The statistical multifragmentation model is modified to incorporate the Helmholtz free energies calculated in the finite temperature Thomas-Fermi approximation using Skyrme effective interactions. In this formulation, the ...
    • Temperature effects in nuclear isoscaling 

      Souza, Sergio Ricardo de Azevedo; Tsang, M. B.; Carlson, Brett Vern; Donangelo, Raul José; Lynch, William G.; Steiner, Andrew W. (2009) [Artigo de periódico]
      The properties of the nuclear isoscaling at finite temperature are investigated and the extent to which its parameter α holds information on the symmetry energy is examined. We show that, although finite temperature effects ...
    • The impact of the uncertainties in the 12C(α, γ ) 16O reaction rate on the evolution of low- to intermediate-mass stars 

      Pepper, Ben Thomas; Istrate, Alina G.; Romero, Alejandra Daniela; Kepler, Souza Oliveira (2022) [Artigo de periódico]
      One of the largest uncertainties in stellar evolutionary computations is the accuracy of the considered reaction rates. The 12C(α, γ ) 16O reaction is particularly important for the study of low- and intermediate-mass stars ...
    • Ultrathin silicon oxynitride film formation by plasma immersion nitrogen implantation 

      Baumvol, Israel Jacob Rabin; Krug, Cristiano; Stedile, Fernanda Chiarello; Green, Martin L.; Jacobson, D.C.; Eaglesham, D.; Bernstein, J.D.; Shao, J.; Denholm, A.S.; Kellerman, P.L. (1999) [Artigo de periódico]
      A method is proposed to prepare ultrathin silicon oxynitride films for gate dielectrics used in deep submicron metal–oxide–semiconductor field effect transistor device structures, namely plasma immersion N implantation ...
