Negative ions are unique quantum systems where electron correlation plays a decisive role
in determining their properties. The lack of optically allowed transitions prevents traditional …

Negative ions, which are formed when an electron is attached to a neutral system, are
unique quantum systems. The lack of a long-range Coulomb force causes the inter …

In this work we have performed Laser Photodetachment Threshold Spectroscopy (LPTS) to
determine the electron affinities of the atomic species 133Cs and 16O with high precision …

Negative ions are unique quantum systems which are of fundamental interest within the field
of atomic physics due to the importance of the electron correlation in their creation, stability …

Negative ions are fascinating quantum systems characterised by a unique electronic
structure compared to their neutral and positively charged counterparts. Investigating these …

Negative ions are of fundamental interest in atomic physics due to the enhanced importance
of the electron correlation. In this thesis new spectroscopic methods have been developed …
