2. 1. Studies of collective phenomena in neutron deficient nuclei : by means of lifetime measurements, angular correlation measurements and the recoil-decay tagging technique

   Author : Karin Andgren; Bo Cederwall; Paul Nolan; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy-ion reactions; multi-detector arrays; recoil separator; in-beam gamma-ray spectroscopy; high spin states; lifetime measurements; recoil-decay tagging; nuclear shape; Nuclear physics; Kärnfysik;

   Abstract : The nucleus is a mesoscopic system that retains features from both the quantum and macroscopic worlds. A basic property of a macroscopic body is its shape. Nuclear shapes can be deduced from experimental data as they influence the excitation mode of the nucleus and hence the energies and lifetimes of its excited levels. READ MORE

4. 2. Molecular electronic,  vibrational and rotational motion in optical and x-ray fields

   Author : Sergey Gavrilyuk; Faris Gelmukhanov; Stephane Carniato; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray; nonlinear optics; photobleaching; recoil; anisotropy; Auger; Chemical physics; Kemisk fysik;

   Abstract : The subject of this theoretical  study is the role ofelectronic structure as well as of rotational and vibrational motionson interactions between molecules and electromagnetic radiation,ranging from optical to x-ray. The thesis concerns both linear and nonlinear regimes of the light-matter interaction. READ MORE

5. 3. Nuclear Dynamics in X-ray Absorption and Raman Scattering

   Author : Ivaylo Minkov; Faris Gelmukhanov; Knut Borve; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray scattering; theory; simulations; recoil; Doppler effect; nuclear dynamics; Auger; XPS; Theoretical chemistry; Teoretisk kemi;

   Abstract : This thesis presents theoretical studies of several x-ray spectroscopies - x-ray absorption, x-ray photoelectron emission, radiative and non-radiative resonant Raman scattering spectroscopy. The main focus point is investigating the influence of nuclear dynamics on these spectra for a variety of small molecules - naphthalene, biphenyl, ethylene, the water dimer, HCl, CO. READ MORE

6. 4. Quantum Nuclear Dynamics in Resonant X-ray Scattering of Gas-Phase and Liquid Systems

   Author : Vinicius Vaz da Cruz; Victor Kimberg; Faris Gel'mukhanov; Hans Ågren; Philippe Wernet; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resonant inelastic X-ray scattering; X-ray absorption; water; methanol; CO; rotational doppler effect; recoil; wave packet; non-Franck-Condon effect; ultra-fast molecular dissociation; potential energy surface; hydrogen bond; liquid; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

   Abstract : This thesis focuses on the role of the nuclear degrees of freedom in X-ray induced molecular processes. An important part of it is devoted to establishing theoretical principles to model and interpret high-resolution resonant X-ray scattering experiments in gases and liquids. READ MORE
