    Nuclear spectroscopy is a superordinate concept of methods that uses properties of a nucleus to probe material properties. By emission or absorption of radiation from the nucleus information of the local structure is obtained, as an interaction of an atom with its closest neighbours. Or a radiation spectrum of the nucleus is detected. Most methods base on hyperfine interactions, which are the. 63 Cu, 65 Cu and 51 V NMR spectra and spin-lattice relaxation rate have been measured in CuV 2 S tion rates 63 (1/T 1) of 63 Cu and 65 (1/T 1) of 65 Cu obey the Korringa law at high temperatures (T ≥ K), and their ratio is very close to the square of the ratio of their gyromagnetic ratios. Below K, 65 (1/T 1) and 63 (1/T 1) increase and diverge due to charge density wave Cited by: 2.

A first-order phase transition with a marked peak at T * ≃ K has been discerned by the specific heat measurement. The observed transition has been connected to a structural change from a simple cubic to a body-centered-cubic superstructure Cited by:

Nuclear Spectroscopy on Charge Density Wave Systems. [Tilman Butz] -- Nuclear magnetic resonance (NMR), nuclear quadrupole resonance (NQR), time differential perturbed angular correlations (TDPAC), and the Mössbauer effect (ME) have been applied to the study of charge.

The existence of charge density wave (CDW) instabilities has been firmly demonstrated for the molybdenum bronzes [2] which include the quasi two dimensional purple bronzes A M0 6 O 17 with A = Li, Na, K, Tl and the quasi one dimensional blue bronzes A M0O 3 with A = K, Rb, Tl.

These latter are maybe the best studied among quasi one dimensional systems in which the charge density waves Author: Claude Berthier, Andraś Jánossy, Patrick Butaud, Pierre Segransan.

The modulation of the electron density changes the ion potential in the lattice so that the ions move to new equilibrium positions. SoCited by: Wolfgang Brütting received his Ph.D.

As the nuclear charge increases to large values, nuclei become more unstable. This is reflected by decreasing half-lives for nuclei heavier than uranium. In K. Petrzak and G. Flerov found that U in addition to α-decay also had a competing mode of radioactive decay termed spontaneous this mode two heavy fragments (fission products) are formed in addition to some neutrons.

Recently, two-dimensional (2D) charge density wave (CDW) materials have attracted extensive interest due to potential applications as high performance functional nanomaterials. As other 2D materials, 2D CDW materials are layered materials with strong in-plane bonding and weak out-of-plane interactions enabling exfoliation into layers of single unit cell by: A compilation of nuclear charge-density-distribution parameters, obtained from elastic electron scattering, is presented in five separate tables.
