Abstract
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. [ABSTRACT FROM AUTHOR]
