Systematic study of the hfs splitings for 3d elements by ABMR-LIRF method — •Przemysław Głowacki, Andrzej Krzykowski, Andrzej Jarosz, Danuta Stefańska, and Jerzy Dembczyński — Chair of Quantum Engineering and Metrology, Poznań University of Technology,
ul. Nieszawska 13B, 60-965 Poznań, Poland

The atomic beam apparatus was donated to our Chair by Prof. W. Ertmer from the Institute of Applied Physics of the University of Bonn, and further modernized and improved. With the use of ABMR-LIRF method (atomic beam magnetic resonance, detected by laser induced resonance fluorescence) and a new magnetic shield in the apparatus, it was possible to obtain the values of the hfs (hyperfine structure) intervals in investigated elements with an accuracy of about 1 kHz [1]. This allowed us to determine precisely the values of the hfs constants A and B (magnetic dipole and electric quadrupole interactions), as well as made the estimation of the values of the hfs constants C (magnetic octupole interaction) for the 3d elements possible.

This work was performed within the framework of DS63-029/10.
