We have observed a strong (2{percent}) angular modulation of the total backscattered conversion electron yield, measured as a function of the incidence angle of the 14.4keV {gamma} rays from a {sup 57}Co M{umlt o}ssbauer source irradiating thin epitaxial {sup 57}Fe film grown on MgO(001). The measured 2D pattern is the first hologram of the local surrounding of the absorbing nuclei obtained due to nuclear resonant scattering of {gamma} rays. The real space holographic reconstruction shows distinct features corresponding to the nearest neighbor sites in the bcc {alpha} -Fe structure. {copyright} {ital 1997} {ital The American Physical Society}
