We have identified some important and worthwhile physics opportunities with a possible neutrino detector located in India.
Particular emphasis is placed on the geographical advantage with a stress on the complimentary aspects with respect to other
neutrino detectors already in operation. 相似文献

Two syntheses of 5-methoxyninhydrin (2,2-dihydroxy-5-methoxy-1,3-indanedione) are described. One method employs a novel and efficient two step route, which begins with commercially available 6-methoxy-1-indanone. The application of this strategy for the preparation of a new ninhydrin derivative, 5-(methylthio)ninhydrin, and ninhydrin is also presented. 相似文献

Improved methodology for the synthesis of benzo[f]ninhydrin (1) is described. The generality of this approach is illustrated with the synthesis of two novel analogs, 6-methoxybenzo[f]ninhydrin (3) and thieno[f]ninhydrin (4). 相似文献

Nuclear magnetic resonance and relaxation, and the related techniques of muon spin rotation and relaxation, have been used to study local spin polarization and quasiparticle excitations in the heavy-fermion superconductors CeCu2Si2, pure and thoriated UBe13, and UPt3. Measurements of nuclear and positive muon Knight shifts, linewidths, and spinlattice relaxation rates give some hints as to the nature of Cooper pairing in these exotic materials. 相似文献

Zero‐field μ+SR and resistivity experiments on La0.67Ca0.33MnO3 powder show that the ferromagnetic transition temperature (TC=274\ K) and resistivity peak temperature coincide to within 1 K, about 10 K higher than TC determined from the bulk magnetization. The sublattice magnetization \nu_μ(T) is well described for T ≤ TC by (1-T/TC)β , where β =0.345 ± 0.015. Unusual relaxation dynamics suggest a wide distribution of Mn‐ion correlation times. These results
are discussed in terms of the effects of polarons on the spin and charge dynamics.

A method has been developed for fabricating fused silica capillary columns which have specific surface properties but still retain the excellent strength, flexibility, and resilience of pure fused silica. By using the Modified Chemical Vapor Deposition process (MCVD), typically used for the production of optical fiber lightguides, inorganic dopants such as Al, Nd, Ge, and P can be introduced into the preform-tube by MCVD. Doped columns have a wide range of specific surface properties, and columns with undoped fused silica prepared by MCVD are more chemically inert and less acidic than columns prepared by conventional methods. This paper describes the method for fabricating capillaries and the initial studies to characterize them. 相似文献
