The proton-rich isotope 146Ho was produced via the fusion-evaporation reaction ^92Mo (^58Ni, 3p1n). The β-delayed proton decay of 146Ho was studied by proton-γ coincidence measurements using a He-jet tape transport system. The γ-transitions in ^145Tb following the proton emissions were observed, and the β-delayed proton branching ratios to the final states in the grand-daughter nucleus ^145Tb were determined. According to the relative branching ratios, the ground-state spin of 146Ho has been proposed and the possible configuration discussed. 相似文献

Using the method developed by Gurvitz [1996 Phys. Rev. B 53 15932], we obtained the Bloch-type rate equations
describing the entire system of a periodically driving qubit monitored by a quantum point contact detector. The results
demonstrate that the isolated qubit can be kept in its initial state with a large driving frequency due to more difficult electron tunneling in qubit, and this initial state can always be measured at a small measurement-induced decoherence rate during a short time. 相似文献

High-spin states in 185Pt have been reinvestigated via the reaction 173Yb(16O, 4n) at a beam energy of 90 MeV. The previously known band based on the ν7/2-[503](f7/2) Nilsson orbital has been extended to higher spin states. Properties of the ν7/2-[503](f7/2) band have been discussed with an emphasis on the evolution of configuration while increasing the spin. 相似文献

Constructing the extracurricular chemistry open experiments for non-major students would help to raise the participation of students in practice instruction, thus benefiting more students. This paper has introduced the construction measures and practical experience about extracurricular chemistry open experiment for non-major students from the following aspects:the attentions in constructing the extracurricular chemistry open experiments for non-major students, the diversified construction of teaching resources and the teaching methods reform. 相似文献

过冷液体和玻璃有着复杂的结构和动力学性质.目前我们对他的研究是很不够的.当液体的温度远低于它的熔点时,它呈现非指数的驰豫行为.大量的实验和分子动力学模拟的研究表明这种非指数的驰豫行为是由动力学不均匀性引起的.计算机模拟已经提供了一些过冷液体的动力学不均匀性的相关信息.而Agell认为,液体可以粘度随温度的变化分为强,弱液体两种.脆性表示的是随着玻璃态的接近液体性质(如黏度)的改变速度.在这篇文章中我们通过模拟了三种不同二元Lennard-Jones液体,计算了它们的非高斯参数,脆性系数等一些参数,研究动了力学不均匀性和脆性的关系.得出了系统的脆性系数越小他的结构就越稳定,动力学不均匀性就越强的结论. 相似文献
