  Title: Beta decay of deformed nuclei with the
proton-neutron finite amplitude method
  Speaker: Thomas Shafer
  Institute: University of North Carolina
  Date: Monday, March 2, 2015
  Time: 4:00 - 5:00 pm EST
  Place: Nieuwland Science Hall, Room 124


In the last few years the finite amplitude method (FAM) has emerged as an efficient technique to calculate nuclear transitions. While formally equivalent to the quasiparticle random-phase approximation (QRPA), the FAM removes the need to construct and diagonalize the large Hamiltonian matrix usually required in the QRPA. As a result, calculations performed with the FAM are significantly faster than their QRPA counterparts, reducing computational burden and enabling larger-scale studies.
At UNC we have recently extended the FAM to calculate beta-decay rates and other charge-changing observables of axially-deformed even-even nuclei. In this talk I will review mean-field theory and the QRPA before discussing the finite amplitude method and its application to beta-decay rates important for r-process nucleosynthesis.
