    Analysis of initial energies of fragments produced by 65-keV proton-molecule collisions using a time-of-flight mass spectrometer

    A method is described to evaluate initial-energy distributions of fragments produced by proton-molecule collisions. The fragments are analysed by means of a time-of-flight mass spectrometer and their initial e...

    Stop** power for Ge ions produced by inelastic scattering of (d,t) fusion neutrons

    Excited72Ge projectiles are produced with 15MeV neutrons from a (d, t) fusion reaction, recoiling within a Ge(Li) detector. The relative response r of the detector on the kinetic energy released by those72Ge ions...

    Electronic stop** cross sections of elements and compounds for swift Li ions

    We report on experimental electronic stop** cross sections of elements and compounds for Li ions. They are measured with the Inverted Doppler Shift Attenuation (IDSA) method with an accuracy of the order of ...

    On the invalidity of Bragg's rule in stop** cross sections of molecules for swift Li ions

    We discuss the invalidity of Bragg's rule for stop** cross sections of molecules for Li ions in the velocity range 1.5 · 108 cm/sec to 4.8 · 108 cm/sec. Here the influence of the chemical bonding in a molecule ...

    On the determination of collision cross sections by nuclear Doppler shift

    We report on measurements of the energy loss of ions in matter by “Inverted Doppler Shift Attenuation” (IDSA). This new method is an inversion of the “Doppler Shift Attenuation” (DSA) method for the determinat...
