Radioactivity - Gamma Decay, Radiation, Particles: A third type of radiation, gamma radiation, usually accompanies alpha or beta decay. Gamma rays are photons and are without rest mass or charge. Alpha or beta decay may simply proceed directly to the gro
The (complete) gamma function is defined to be an extension of the factorial to complex and real number arguments. It is related to the factorial by (1) a slightly unfortunate notation due to Legendre which is now universally used instead of Gauss's simpler (Gauss 1812; Edwards 2001, p...
Therefore, remeasurement of the individual k 0 -factors was carried out by using a high-performance Ge-detector and a gamma-spectrum analysis program with proven accuracy. This study involved a number of gamma lines of radionuclides for the determination of some 10 elements among which Mo, Pd,...
Lithium fluoride (LiF), one of the most pervasive alkali halides in optical device research, is routinely used in optical data storage and radiation protection. LiF crystals may contain different aggregate defects produced by several types of ionizing radiation, with the number of defects being propo...
Previous studies that attempted to address this question using magnetoencephalography (MEG)26,27, EEG28,29,30 and functional magnetic resonance imaging (fMRI)10,31 in humans have a number of limitations. Brief stimulation during sleep elicits a large stereotypical response—an evoked slow wave often...

A gamma wave is considered to be the fastest brain activity. It is responsible for cognitive functioning, learning, memory, and information processing. Prominence of this wave leads to anxiety, high arousal, and stress; while its suppression can lead to Attention Deficit Hyperactivity Disorder (ADHD...

The precise value of the thermal capture cross section of ~(238)Uis uncertain, and evaluated cross sections from various sources differ by more than their assigned uncertainties. A number of the original publications have been reviewed t... A. Trkov,G. L. Molnar,Zs. Revay,... - 《Nuclea...
