External Properties of Atomic Nuclei Äussere Eigenschaften Der Atomkerne

Nuclear magnetic resonance spectroscopy (NMR spectroscopy) is a research technique that uses the magnetic properties of atomic nuclei to determine physical and chemical properties of atoms or the molecules in which they are contained.

In Hearing of is the third album by British rock band Atomic Rooster. Although not included on the album, "The Devil's Answer" single was released just prior to it, becoming the band's highest chart success at number 4 in the UK. This helped push the album to a number 18 UK chart placing, despite the fact that the four musicians pictured on the inside cover never played together. The backing tracks (and some vocals) were recorded by Vincent Crane, John Cann and Paul Hammond, but Cann and Hammond left the group soon after vocalist Pete French was drafted in. The finished album's sound was dominated by Crane and Hammond, with many of Cann's guitar parts either not used or placed lower in the mix. In addition, many of the songs were written by Crane, along with his first wife, Pat Darnell.

This book reports the establishment of a single-atomic layer metal of In and a novel (In, Mg) ultrathin film on Si(111) surfaces. A double-layer phase of In called “rect” has been extensively investigated as a two-dimensional metal. Another crystalline phase called “hex” was also suggested, but it had not been established due to difficulty in preparing the sample. The author succeeded in growing the large and high-quality sample of the hex phase and revealed that it is a single-layer metal. The author also established a new triple-atomic layer (In, Mg) film with a nearly freestanding character by Mg deposition onto the In double layer. This work proposes a novel method to decouple ultrathin metal films from Si dangling bonds.

One of the indicators of the level of technological development of a society has been, throughout history, the precision of clocks it was able to build. This book examines the physical principles underlying the workings of clocks–from the earliest mechanical clocks to the present-day sophisticated clocks based on the properties of individual atoms. Intended for non-specialists with some knowledge of physics or engineering,the book treats the material in a broad intuitive manner, with a minimum of mathematical formalism. The presentation covers a broad range of salient topics relevant to the measurement of frequency and time intervals. The main focus is on electronic time-keeping: clocks based on quartz crystal oscillators and, at greater length, atomic clocks based on quantum resonance in rubidium, cesium, and hydrogen atoms, and, more recently, mercury ions. The book treats the revolutionary changes that the optical laser has wrought on atomic standards through laser cooling and optical pumping, and it discusses the application of these clocks to global navigation–in particular Loran-C and the Global Positioning System. The book also touches on such topics as atomic resonance line shape, the relativistic Doppler effect and general notions of time, including the relativity of future and past, the clock paradox, the Sagnac effect and finally, time reversal symmetry.
