The angular distributions of gamma rays and alpha particles from oriented Bk-250, Es-253,Es-254, and Fm-255 nuclei were investigated to extract hyperfine interaction information for these actinide impurities in an iron host lattice. The hyperfine field of einsteinium in iron was found to be |B-hf(EsFe_|)=396(32) T. With this value the magnetic moment of Es-254 was then determined as |mu|=4.35(41) mu(N)./p.

Úhlové distribuce záření gama a alfa částic z orientovaných jader Bk-250, ES-253, ES-254 a Fm-255 byly zkoumány za účelem zjištění informací o velmi jemné interakci těchto aktinidových nečistot v železné mříži. Bylo změřeno hyperjemné pole einsteinia v železe | B-hf (EsFe_ |) = 396 (32) T. S touto hodnotou pak byl stanoven magnetický moment Es-254 mu | = 4,35 (41) mu ( N).
