Richard Gordon FitzGerald Uniacke, FRSAI (19 August 1867 – 11 November 1934) [1] was a British genealogist and librarian. He was the eldest son of the Rev. Robert FitzGerald Uniacke, late vicar of Tandridge, Surrey , a descendant of an old Irish family, the Uniackes of Uniacke and Castleton, County Cork. [ 2 ]
This was in a gold atom known to be 10 −10 metres or so in radius—a very surprising finding, as it implied a strong central charge less than 1/3000th of the diameter of the atom. The Rutherford model served to concentrate a great deal of the atom's charge and mass to a very small core, but did not attribute any structure to the remaining ...
The adoption of the term "nucleus" to atomic theory, however, was not immediate. In 1916, for example, Gilbert N. Lewis stated, in his famous article The Atom and the Molecule, that "the atom is composed of the kernel and an outer atom or shell." [12] Similarly, the term kern meaning kernel is used for nucleus in German and Dutch.
Illustration of the Jaynes–Cummings model. An atom in an optical cavity is shown as red dot on the top left. The energy levels of the atom that couple to the field mode within the cavity are shown in the circle on the bottom right. Transfer between the two states causes photon emission (absorption) by the atom into (out of) the cavity mode.
The optical spectrum of the two electron atom has two systems of lines. A para system of single lines, and an ortho system of triplets (closely spaced group of three lines). The energy levels in the atom for the single lines are indicated by 1 S 0 1 P 1 1 D 2 1 F 3 etc., and for the triplets, some energy levels are split: 3 S 1 3 P 2 3 P 1 3 P ...
In a simulation, the potential energy of an atom, , is given by [3] = (()) + (), where is the distance between atoms and , is a pair-wise potential function, is the contribution to the electron charge density from atom of type at the location of atom , and is an embedding function that represents the energy required to place atom of type into the electron cloud.
The estate was built as a country residence for Richard John Uniacke, Nova Scotia's Attorney-General during the War of 1812.Located along the "Post Road", the original road between Halifax and Windsor, the site was, according to Uniacke's s family, selected in 1776 while Uniacke being taken to Halifax in chains to face a treason trial for siding with the rebels in the Battle of Fort Cumberland.
