The reaction d(~γ, np) has been studied using the tagged and polarised LADON gamma ray beam at an energy 30− 50 MeV to investigate the existence of narrow dibaryonic resonances recently suggested from the experimental measurements in a different laboratory. The beam was obtained by Compton back-scattering of laser light on the electrons of the storage ring ADONE. Photo-neutron yields were measu...

We study the hyperfine splitting of an electron in hydrogen-like 209 Bi 82+. It is found that the hfs energy splitting can be explained well by considering the g-factor reduction due to the binding effect of a bound electron. We determine for the first time the experimental value of the magnetic moment of a tightly bound electron.
