Rutherford, Lord Ernest

RBS is based on collisions between atomic nuclei and derives its name from Lord Ernest Rutherford who first presented the concept of atoms having nuclei. When a sample is bombarded with a beam of high-energy particles, the vast majority of particles are implanted into the material and do not escape. This is because the diameter of an atomic nucleus is on the order of 10 A while the spacing between nuclei is on the order of 1 A. A small fraction of the incident particles do undergo a direct collision with a nucleus of one of the atoms in the upper few pm of the sample. This collision actually is due to the Coulombic force present between two nuclei in close proximity to each other, but can be modeled as an elastic collision using classical physics. [Pg.477]

Daniel Rutherford (1749—1819), Scotch botanist, first identified nitrogen (Ref 58, p 113). Do not confuse with Lord Ernest Rutherford (1871—1937), Brit physicist noted for his research on radioactive transformation and disintegration of nitrogen... [Pg.132]

The atomic numbers of these isotopes were identified by detecting the known No daughters of these nuclei. The group suggested the name of rutherfordium (chemical symbol Rf) for element 104 in honor of Lord Ernest Rutherford. [Pg.442]

The book is titled Polymer Physics largely because the authors share the viewpoint of Lord Ernest Rutherford ... [Pg.451]

The fact that the positive charge of the atom resides in a dense, tiny nucleus was discovered in 1911 by the English physicist Lord Ernest Rutherford. [Pg.68]

Lord Ernest Rutherford was born in New Zealand in 1871, but went to Cambridge University in England to pursue his Ph.D. in physics in 1895. His original interest was in a phenomenon that we now call radio waves, and he apparendy hoped to make his fortune in the field, largely so he could marry his fiancee back in New Zealand. However, his professor at Cambridge, J.J. Thomson, convinced him to work on the newly discovered phenomenon of radioactivity. Rutherford discovered alpha and beta radiation while at Cambridge. In 1899, he moved to McGill University in Canada where he did further experiments to prove that alpha radiation is actually composed of helium nuclei and that beta radiation consists of electrons. For this work he received the Nobel Prize in chemistry in 1908. [Pg.44]

During the 1920s, Lord Ernest Rutherford had suggested that a heavy hydrogen isotope could exist, and there was some evidence for this idea. The American scientist Harold Clayton Urey found that if liquid hydrogen was fractionally distilled, he could obtain a fraction richer in the heavier isotope, and when he examined the atomic spectrum of these samples, he detected lines that were not due to ordinary hydrogen, thus were caused by the presence of small amounts of deuterium (D). [Pg.218]

RBS is based on collisions between atomic nuclei and derives its name from Lord Ernest Rutherford, who in 1911 was the first to present the concept of nuclei in atoms. It involves measuring the number and energy of ions in a beam, which backscatter after colliding with atoms in the near-surface region of a sample where the beam has been targeted. With this information, determining atomic mass and elemental concentrations versus depth below the surface is possible. RBS is ideally suited for determining the concentration of trace elements heavier than major... [Pg.34]

Rutherford continued to do research until his death, but the proton was his last big discovery. It was not, however, his last big honor. In 1931, the New Zealand country boy was raised to the peerage with the official name of Ernest, Lord Rutherford of Nelson. After his death six years later, he was awarded one last honor. He was buried in Westminster Abbey, where he keeps company with Isaac Newton and a handful of other great British scientists. [Pg.31]

Rutherford won many awards for his work as a scientist and teacher. He won the Nobel Prize for chemistry in 1908 and was knighted in 1914. In 1919 he became the Cavendish Professor of Physics at Cambridge. He was made Lord Rutherford of Nelson in 1931. Rutherford died at Cambridge on October 19, 1937. see also Bohr, Niels Marsden, Ernest Soddy, Frederick Thomson, Joseph John. [Pg.1125]
