项目摘要

The target of this research project is to develop the precise atomic magnetometer with the hybrid setup of spin-polarized Xe and Rb atoms. To utilize Xe atoms with intrinsically-long spin-relaxation time, it is necessary to preserve atoms at high density for a long time without loss of spin-polarization. I came up with the idea to solvate the hyperpolarized Xe atoms in some liquid where much higher density can be realized as gas phase at normal condition. The mechanism of spin-relaxation in solution, nuclear dipole interaction and spin-rotation interaction with solvent molecules, as well as wall relaxation was found. Wall relaxation is mostly dominant in spin-relaxation process since enormous numbers of past works cleared up the relaxation mechanism in gas-phase. We would get extremely high polarization of gaseous atoms if we overcame the wall relaxation. Our high field NMR measurement is one of hopes to lead us to understand the spin interaction at the walls. We are able to regenerate phase diagram of metal-impurities alloy by detecting Knight shift near the melting points of pure metal. Then, we assigned that two species of impurities can solve in alkali-metal in the glass cells. One is oxygen atoms. Once oxygen atoms solved into alkali-metal, the trace oxygen homogeneously takes electron from conduction band of metal. Since the electron density at surface is related to the nuclear spin relaxation of ^3He atoms, our finding gave as the technique to control precisely the oxygen density and to develop novel coating materials on the glass surface. In addition to wall relaxation mentioned above, we discovered the new phenomenon that the angular momentum can be transferred to a solid. By optically pumping gaseous Cs atoms, Cs nuclei of CsH salt was found to be polarized as 19-times as thermal equilibrium at 2.7T and 100℃.
本研究计画的目标是利用自旋极化的铷原子与铷原子的混合装置,研制出精密的原子磁力计。为了利用具有本质上长的自旋弛豫时间的双金属原子,需要将原子长时间保持在高密度而不损失自旋极化。我想出了一个想法,在一些液体中溶剂化超极化的双原子,在正常条件下,气相可以实现更高的密度。发现了溶液中的自旋弛豫机制、核偶极相互作用、与溶剂分子的自旋-旋转相互作用以及壁面弛豫机制,其中壁面弛豫在自旋弛豫过程中占主导地位,而气相中的弛豫机制已被大量工作所阐明。如果我们克服壁弛豫,我们将得到极高的气体原子极化。我们的高场核磁共振测量是一个希望,带领我们了解自旋相互作用的墙壁。通过检测纯金属熔点附近的Knight位移,我们可以重建金属-杂质合金的相图。在此基础上,我们确定了两种杂质在玻璃池中可以溶解在碱金属中。一个是氧原子。一旦氧原子溶解到碱金属中,微量的氧均匀地从金属的导带中带走电子。由于表面的电子密度与^3He原子的核自旋弛豫有关,我们的发现为精确控制玻璃表面的氧密度和开发新型涂层材料提供了技术。除了上述壁面弛豫外,我们还发现了角动量可以转移到固体中的新现象。在2.7T和100℃下,用光泵抽运气态Cs原子,发现CsH盐中Cs原子核的极化率是热平衡态的19倍。
