Superheavy elements

The paper deals briefly with the results of a series of theoretical and experimental studies on the search for superheavy elements (Z=114, N=184). A hypothesis on relation between shell structure of initial nuclei with analogous characteristic of their fission fragments is suggested. According to this hypothesis the twice magic nucleons Z=114, N=184 preferentially is divided into fragments caused by magic numbers Z=28 (or 32), N=50 and Z=82, N=126. As the experience of 258Fm and 259Fm nuclei study has shown fragments ''magic'' to a great extent destabilizes the initial nucleus. It is not excluded therefore that instead of stability island there exists instability crater with coordinates Z=114, N=184
