Abstract (english)

In this work, the effect of temperature on Gamow–Teller strength is investigated using fully self-consistent finite temperature proton-neutron random phase approximation in the 56Fe nucleus. The calculations are performed with Skyrme-type SkM* interaction at T = 0, 1, and 2 MeV. It is shown that temperature effects of the occupation probabilities of states and new excitation channels become possible due to the smearing of the Fermi surface. The Gamow–Teller excitation energies shift downward and new excited states are also obtained in the low-energy region due to the unblocked transitions at high temperatures.
