Measurements of inelastic proton scattering with high energy resolution at forward scattering angles including 0 degrees are described. High-resolution halo-free beams were accelerated by the cyclotron complex at the Research Center for Nuclear Physics. Instrumental background events were minimized using the high-quality beam. The remaining instrumental background events were eliminated by applying a background subtraction method. As a result, clean spectra were obtained even for a heavy target nucleus such as Pb-208. A high energy resolution of 20 keV (FWHM) and a scattering angle resolution of +/- 0.6 degrees were achieved at an incident proton energy of 295 MeV. (C) 2009 Elsevier B.V. All rights reserved.

Experimental technique for measuring proton inelastic scattering with high-resolution at 295 MeV and at forward angles including zero degrees have been successfully developed. An excitation energy resolution of less than 20 keV, good scattering angle resolution, low background condition, and reasonable background subtraction have been achieved. The experimental technique have been applied for several sd and pf shell nuclei for systematic study M1 and E1 excitations in nuclei. The experimental method and preliminary spectra are reported.

The motion of boiling liquid nitrogen (LN2) between electrodes and its surface profile in a microgravity environment just after release from terrestrial gravity are observed. The dynamic behaviour is analysed considering the following forces: the Maxwell stress, surface tension and viscosity, and is explained consistently by theory including these forces. The velocity of the liquid driven by the Maxwell stress and the capillary force (surface tension) is compared with that driven by the capillary force only. The growth dynamics of bubbles produced on the surface of electrodes is discussed.
