    Although a suction vortex is the one of the most common vortices appearing in our everyday life, its internal structure has not been fully understood yet. One of the few things that we understand is that the radius of the core results from the competition between the diffusion of the vorticity due to the kinematic viscosity and the transportation of the vorticity due to the inward flow. To understand the structure of the suction vortex, we investigated a suction vortex produced in liquid helium. In the normal fluid phase, liquid helium behaves as a viscous fluid. In contrast, in the superfluid phase, a quantum vortex line carries all the microscopic circulation, and the suction vortex can be understood as a complex of quantized vortex lines. We generated a superfluid suction vortex with a cryogenic turbine and measured its circulation with a pulsed first sound circulation meter, and also measured the vorticity by the second sound attenuation technique. The experimental results indicate that the quantized vortex lines accumulated in the narrow region around the axis of symmetry due to an inward flow, the core structure of which cannot be described by a simple bundle of fully polarized quantized vortex lines.

    To investigate whether it is possible to control the wetting of He-4 crystals on a wall in superfluid, the contact angles of He-4 crystals were measured on rough and smooth walls at very low temperatures. A rough wall was prepared in a simple manner in which a commercially available coating agent for car mirrors, which makes the glass surface superhydrophobic, was used to coat a glass plate. The contact angles of He-4 crystals were increased by approximately 10 degrees on the rough wall coated with the agent. Therefore, the increase in the repellency of He-4 crystals in superfluid was demonstrated to be possible on a very rough surface. The enhancement of the contact angles and a scanning electron microscopy image of the coated surface both suggest that a Cassie-Baxter state of He-4 crystals was realized on the surface; the crystals did not have full contact with the wall, but entrapped superfluid was present beneath the crystals in the hollow parts of the rough wall.

    In superfluid He-3-A, it was theoretically predicted that the half-quantum vortex (HQV) is stable where the order parameters (d) over cap and (l) over cap are perpendicular to each other in the order parameter configuration. However, the existence of the HQV has not been reported experimentally. Now we are trying to detect the HQV in superfluid He-3-A confined in the parallel-plates sample cell with 12 mu m gap, where (d) over cap and (l) over cap are perpendicular to each other, by using a NMR technique under a rotation at ISSP. In order to detect the HQV, we improved the magnet system for NMR so far, but we have not observed the HQV yet. We report here the experimental details and some results for investigating the HQV.

    We have studied phase transition of superfluid He-3 at 2.4 MPa in cylindrical aerogel by NMR method. When the liquid is cooled down from the normal state, the A-like phase appears below superfluid transition temperature T-c(a) which is suppressed in comparison with the transition temperature of the bulk liquid. With further cooling below the certain temperature T-ab,c(a), the A-like phase is converted into the B-like phase gradually. Both phases stably coexist within about 90 mu K. When you keep the temperature constant in which both phases coexist, the A-B phase conversion stops. With furthermore cooling, the whole liquid becomes the B-like phase. The cwNMR spectra at the coexistence state suggest that the B-like phase is not uniformly distributed in the A-like phase like a large number of small bubbles in a liquid, but separated as a whole from the A-like phase. By applying a field gradient which changes as a function of square of radius, we found that the A-like phase is in the edge part with a cylindrical shape and the B-like phase is in the central part with a columnar shape.

    Phase transition in superfluid He-3 in aerogel has been studied by NMR. Above 19 bar, we have clearly observed the A-like and B-like phases by following changes in the NMR lineshapes and resonance frequencies. There is a wide temperature region in which the A-like phase and the B-like phase coexist extending from near the superfluid transition temperature T-c(aero) to the lowest temperature of coexistence, T-AB(aero), below which only the B-like phase exists. There are two temperature regions, only in which the phase conversion occurs. Both regions are a few tens of mu K wide, the upper region being just below T-c(aero) and the lower one just above T-AB(aero). In cooling down and warming up with the two phases in coexistence, no phase conversion occurs between the two regions. The phase boundary between the A-like phase and B-like phase cannot move in aerogel due to strong pinning by inhomogenities of aerogel.

    バラを凍らせたらバリバリと手で割ることができる、という映像を見たことがある人は多いだろう。しかし、どうしてそうなるのか、そしてその後バラはどうなるのか、きちんと説明できる人はいるだろうか? そもそも、凍らせるとはどういうことか、温度とは何か、自然環境において温度とはどういう意味を持つのか、様々な実験を通して考えてみよう。
    温度とは何か? 物質を冷却するとどうなるか? という疑問を通して、自然科学の根本原理の一部を理解する。
    子供の「理科離れ」が起きるのは主に中学1年生であるというデータがある。学習内容が大きく変化し、また、自然を理解するという学問から試験対策へと変化する時期でもある。これは小学校・中学校教員の問題ではなく、社会全体の問題である。子供たちは、多かれ少なかれ、実験が好きだが、あいまいで多くの場合間違った「素朴理論」で自然を理解したつもりでいる。これを、自然「科学」に昇華させることができれば、理科離れは防ぐことができるはずである。これまでの経験から、液体窒素を用いた冷凍実験に興味を示さなかった児童・生徒は皆無である。しかし、実験が実験だけで終わってしまうのなら、単なるエンターテイメントである。私は、エンターテイメント性を最大限残しつつ、自然科学一般へ興味の目を向けさせ続けるモチベーションとなるような講座を開講したいと思っている。小学校・中学校において液体窒素を使った低温実験を行いたいと考えている先生方にも、ノウハウと背景にある物理法則についての助言ができればよいと考えている。
