Seminars
Seminar on low-energy nuclear physics
Date and Time: Friday, 24 April 2023, at 3:30 PM
Venue: Blokhintsev Hall (4th floor), Bogoliubov Laboratory of Theoretical Physics, online on Zoom
Seminar topic: “Electric 1+ state below nuclear scissors”
Speakers: Evgeny Balbutsev, Irina Molodtsova
Abstract:
The solution of time dependent Hartree-Fock-Bogoliubov equations by the Wigner function
moments method predicts four low-lying 1+ states. Three of them are known as various scissors modes.
Fourth state is disposed below all scissors modes and has the electrical nature. It is found that it
represents one of three branches of 2+ state which can exist in spherical nuclei and which is split
in deformed nuclei. It is discovered, that the antiferromagnetic properties of nuclei lead to the splitting
of 2+ states already at the zero deformation.
