TEMPERATURE AND FREQUENCY DEPENDENCES OF NMR SPIN-LATTICE RELAXATION TIME T1 IN a-Si : H
Carlos and Taylor have recently reported pulsed ' H NMR measurements on the spin-lattice relaxation time T for the hydrogen atoms in glow discharge prepared a-Si:H. They have measured 40th the magnitude and the temperature and frequency dependences of T1 and observed a number of interesting features. Among these are the presence of an asymmetric minimum in T1 at a temperature T . near 40K which...
متن کاملNQR Spin-Lattice Relaxation of Re in Perrhenates
The temperature dependence of the spin-lattice relaxation time Tx for the Re NQR in K R e0 4 , N H 4R e 0 4 and N D 4R e 0 4 has been measured between 77 K and 323 K. The relaxation is electric quadrupolar in all cases, and because of the large quadrupole moment of Re, 7i is short. In K R e0 4 Ti follows a T 2 dependence. In N H 4R e 0 4 , Ti decreases more rapidly than T ~ 2 above about 100 K;...
متن کاملTemperature dependence of the Spin-Lattice Relaxation Time
The spin-lattice relaxation time, TX, of the 2 3 N a N M R line in N a N 0 2 is measured between 25 K and 160 K at two magnetic field strengths, 1.1 T and 6.9 T. The temperature dependence of TX for the center line, observed on a polycrystalline sample prepared by precipitation from aqueous solution, is given by a monotonous curve. Tx increases gradually as the temperature decreases. On the oth...

15 صفحه اول: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
