   Sammanfattning : Necrotising enterocolitis (NEC) is a potentially devastating intestinal inflammation of multifactorial aetiology in premature or otherwise vulnerable neonates. Because of the broad spectrum of presentations, diagnosis and timing of surgical intervention may be challenging, and imaging needs to be an integrated part of management. LÄS MER

3. 2. Rotationally cold molecular ions in DESIREE : Threshold photodetachment thermometry of OH− and OD−

   Sammanfattning : In experiments on molecular ions it is highly beneficial if the ions are in the electronic, vibrational and rotational ground state. Previous studies on these systems in ion traps or storage rings have been successful in preparing the molecular ions in the electronic and vibrational ground states, but the rotational degrees of freedom are experimentally more challenging due to their long relaxation times and the relatively small amounts of energy required for rotational excitations.
