STUDY OF NUCLEAR LEVEL DENSITY AND SPIN CUT-OFF FACTORS
Nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹A‹63,from a microscopic theory, which includes nuclear pairing interaction. Single particle levels for both Seeger and Nilsson potentials were used in the calcdations. Level densities extracted from the theory are compared with their conesponding experimental values, It is found that the overall...
متن کاملComputer-generated character tables and nuclear spin statistical weights: application to benzene dimer and methane dimer
In the assignment of high-resolution spectra of van der Waals molecular clusters, it is of great utility to know the character table of the molecular symmetry group and the nuclear spin weights of the various rovibronic symmetry species [1]. While their calculation is not difficult, for large groups it is lengthy [2] and prone to errors due to the sheer quantity of variables involved. For the b...
متن کاملNuclear double resonance between statistical spin polarizations.
We demonstrate nuclear double resonance for nanometer-scale volumes of spins where random fluctuations rather than Boltzmann polarization dominate. When the Hartmann-Hahn condition is met in a cross-polarization experiment, flip-flops occur between two species of spins and their fluctuations become coupled. We use magnetic resonance force microscopy to measure this effect between 1H and 13C spi...
متن کاملNuclear spin diffusion in a rare spin species
2014 We derive an approximate theory for the spin diffusion tensor in a rare nuclear spin species imbedded into an abundant one, with special reference to 43Ca in CaF2. The usefulness of the theory is examplified by the description of an investigation of ferromagnetism with domains of the 19F spins, where the knowledge of the 43Ca spin diffusion constant allows a determination of the ferromagne...
