The modern version of atomic structure begins withErnest Rutherford’srecognitionthat an atom consists of a single, central, massive, positively charged nucleus surrounded by electrons. The number ofprotonsin the nucleus is theatomic number,Z, of the element. (ForhydrogenZ= 1, and forcarbonZ= ...

The invention relates to a reactor for consuming a nuclear fuel that contains atoms of elements having a low atomic number (Z) and a low mass number (A), wherein the nuclear reactor ( 1 ) comprises a vessel ( 2 ) containing a reaction chamber ( 3 ). This reaction chamber ( 3 ) is...
The WT maximum is known to be affected by the path length R, Debye–Waller factors σ2, energy shift ΔE and atomic number Z, and this corresponds to the same location of the maximum in the q-space magnitude30. For an isolated Co–C path (R=2 Å), the WT maximum at 3.2...
