The overlaps between these non-orthonormal states form a special matrix coincidental with the one obtained by Rowe and Rosensteel. They proposed a proposition related to the eigenvalue problems of that matrix and dimensions of the associated subspaces. We prove their proposition with the help of the symmetric properties of the six-j symbols. We also derive algebraic expressions for eigen energies as well as conditions for conservation of seniority through the decomposition of the angular momentum.展开更多

Accordingly, pairing forces in the form of surface delta interaction are employed to account for the formation of the ground state multiplet with seniority v= 2 states. The multiplet splitting is described with mass relationships of masses of neighboring nuclei. Subsequently, the seniority model is adopted to reproduce or predict the states v= 3 in odd-even isotopes and v= 4 in even-even isotopes. The correct account of the 2^(+)_(1) state should allow for the description of the reversed order of J = 4 states with v= 2 and v= 4 observed in experiments. The results obtained are compared with the structure of similar multiplets in N=50 isotones.展开更多

During his 70 years of clinical practice, he developed the theory that most diseases are caused by qi stagnation, and in order to restore qi circulation one needs to improve the blood circulation first. Based on this theory, in combination with empirical insights from clinical practice, he has developed a unique technique for using three-edged needles. He has also categorized and extended the application of bloodletting therapy with three edged needles to cover over 150 diseases. In addition, Dr. He＇s bloodletting therapy with three edged needles is an innovation that may inspire other physicians to develope and expand the use of acupuncture-related therapies to treat disease.展开更多

文摘In this paper we study the system with three nucleons within a single-j shell, which can be described as the angular momentum coupling of a nucleon pair and the odd nucleon. The overlaps between these non-orthonormal states form a special matrix coincidental with the one obtained by Rowe and Rosensteel. They proposed a proposition related to the eigenvalue problems of that matrix and dimensions of the associated subspaces. We prove their proposition with the help of the symmetric properties of the six-j symbols. We also derive algebraic expressions for eigen energies as well as conditions for conservation of seniority through the decomposition of the angular momentum.

文摘Excited states in low-energy spectra of ^(70-76) Ni are considered. Accordingly, pairing forces in the form of surface delta interaction are employed to account for the formation of the ground state multiplet with seniority v= 2 states. The multiplet splitting is described with mass relationships of masses of neighboring nuclei. Subsequently, the seniority model is adopted to reproduce or predict the states v= 3 in odd-even isotopes and v= 4 in even-even isotopes. The correct account of the 2^(+)_(1) state should allow for the description of the reversed order of J = 4 states with v= 2 and v= 4 observed in experiments. The results obtained are compared with the structure of similar multiplets in N=50 isotones.
