利用仲氢和钕磁体制成的机械压力机，我们成功地制作了厚度为1 mm、直径为30 mm的固体氢靶（SHT），并测量了质子与300 MeV/u放射性离子束的弹性散射。我们还成功地制作了厚度为0.5 mm、直径为10 mm的SHT和厚度为2 mm、直径为30 mm的SHT，用于研究中能核（p，p′）反应和准自由（p，pα）反应的激发态性质。正-对位转换器和简单的机械压力机显示了制造具有各种半径和厚度的SHT的可能性。
By using para-hydrogen and a mechanical press made of neodymium magnets, we have succeeded in making a 1-mm-thick and 30-mm-diameter solid hydrogen target (SHT), and have measured elastic scattering of protons with radioactive ion beams at 300 MeV/u. We also succeeded in making not only a 0.5-mm-thick and 10-mm-diameter SHT but also a 2-mm-thick and 30-mm-diameter SHT to study excited-state properties of nuclei via (p,p′) reactions, and quasi-free (p,pα) reactions at intermediate energies. The ortho–para converter and the simple mechanical press show possibilities for making SHTs which have various radii and thicknesses.
