Uncovering highly excited states of quantum three body systems using new technological approaches. Experimental studies of the fundamental structure of quantum three body systems are proposed to uncover long-lived highly-excited states. Ultra-fast timing technology applied to a variant of electron time-of-flight studies will form the basis of the measurement system to be used at a world-class synchrotron light source.
Sub-picosecond studies of matter using intense light from a Free Electron Laser. An Australian research group will use their new ultra-fast timing technology in combination with a new, extremely bright light source, the FERMI Free Electron Laser, Italy. FERMI makes picosecond wide light pulses - the timing technology measures times significantly shorter than a nanosecond. In combination, the way intense light effects the structure of atoms & molecules is studied, leading to an in-depth understa ....Sub-picosecond studies of matter using intense light from a Free Electron Laser.

In combination, the way intense light effects the structure of atoms & molecules is studied, leading to an in-depth understanding of the processes involved. The new detector technology will be characterised using an electron recycling spectrometer, a new method for making electron beams of a particular energy by storing electrons in a racetrack orbit.Read moreRead less

Revealing the mechanism of heavy ion stopping at high energies. Several fundamental aspects of heavy ion stopping in matter, which is important for many technological and medical applications, are not understood. This includes the charge dependence of ion stopping known as Barkas effect, the Bloch-contribution to the stopping cross-section, and charge exchange processes. In contrast to other studies, the use of crystalline materials with well-defined atom locations and the application of new sop ....Revealing the mechanism of heavy ion stopping at high energies. Several fundamental aspects of heavy ion stopping in matter, which is important for many technological and medical applications, are not understood. This includes the charge dependence of ion stopping known as Barkas effect, the Bloch-contribution to the stopping cross-section, and charge exchange processes. In contrast to other studies, the use of crystalline materials with well-defined atom locations and the application of new sophisticated models will allow the separation of these related phenomena, so that they can be studied individually. This will reveal details of the physical mechanisms governing the energy dissipation by fast heavy ions in matter.

Quantum Entanglement of Protons Studied by Electron Scattering at High Momentum Transfer. Eighty years after the establishment of quantum mechanics protons in matter are still largely seen as 'classical' particles, that do not interfere in ways known to occur for light and electrons. There are indications from neutron and electron scattering experiments from solids that, for extremely short time scales, (one-millionth of a nanosecond), this picture is too simple. The proposed experiment seeks t ....Quantum Entanglement of Protons Studied by Electron Scattering at High Momentum Transfer. Eighty years after the establishment of quantum mechanics protons in matter are still largely seen as 'classical' particles, that do not interfere in ways known to occur for light and electrons. There are indications from neutron and electron scattering experiments from solids that, for extremely short time scales, (one-millionth of a nanosecond), this picture is too simple. The proposed experiment seeks to establish this fact for molecules in the gas-phase. As the chemical bond is formed at similar time-scales these experiments will improve our understanding of chemical reactions, and hence be of great value for the chemical industry.Read moreRead less
