Temperature effects on nuclear pseudospin symmetry in the Dirac-Hartree-Bogoliubov formalism
R. Lisboa, P. Alberto, B. V. Carlson +1
We present finite temperature Dirac-Hartree-Bogoliubov (FTDHB) calculations for the tin isotope chain to study the dependence of pseudospin on the nuclear temperature. In the FTDHB…
Spin and pseudospin symmetries in the antinucleon spectrum of nuclei
R. Lisboa, M. Malheiro, P. Alberto +2
Spin and pseudospin symmetries in the spectra of nucleons and antinucleons are studied in a relativistic mean-field theory with scalar and vector Woods-Saxon potentials, in which t…
Relating pseudospin and spin symmetries through charge conjugation and chiral transformations: the case of the relativistic harmonic oscillator
A. S. de Castro, P. Alberto, R. Lisboa +1
We solve the generalized relativistic harmonic oscillator in 1+1 dimensions, i.e., including a linear pseudoscalar potential and quadratic scalar and vector potentials which have e…
Tensor coupling and pseudospin symmetry in nuclei
P. Alberto, R. Lisboa, M. Malheiro +1
In this work we study the contribution of the isoscalar tensor coupling to the realization of pseudospin symmetry in nuclei. Using realistic values for the tensor coupling strength…
Perturbative breaking of the pseudospin symmetry in the relativistic harmonic oscillator
R. Lisboa, M. Malheiro, A. S. de Castro +2
We show that relativistic mean fields theories with scalar, , and vector, , quadratic radial potentials can generate a harmonic oscillator with exact pseudospin symmetry {\it…
The nuclear pseudospin symmetry along an isotopic chain
R. Lisboa, M. Malheiro, P. Alberto
We investigate the isospin dependence of pseudospin symmetry in the chain of tin isotopes (from Sn until Sn). Using a Woods-Saxon parametrization of the nuclear pot…
