This review provides a comprehensive overview of the applications of helium nanodroplets
in the study of ensembles of atoms and molecules, ie clusters and complexes. These …

Abstract In this Topical Review we survey the current state of the art in the study of low
energy electron collisions with biologically relevant molecules and molecular clusters. We …

Helium droplets represent a cold inert matrix, free of walls with outstanding properties to
grow complexes and clusters at conditions that are perfect to simulate cold and dense …

We demonstrate a novel method to ionize molecules or molecular clusters by proton transfer
at temperatures below 1 K. The method yields nascent ions and largely eliminates …

In biological tissues, ionizing radiation interacts with a variety of molecules and the
consequences include cell killing and the modification of mechanical properties …

We report the results of an experimental study of electron ionization of large helium
nanodroplets doped with formic acid (FA). Several homologous series of cluster anions are …

Fragmentation of transient negative ions of tyrosine formed through electron transfer in
collisions with neutral potassium atoms is presented in the collision energy range from 30 to …

Formation of fragment ions due to single and dissociative ionization of the valine molecule
(C _ 5 H _ 11 NO _ 2) C 5 H 11 NO 2) by electrons was studied by mass spectrometry. This …

Independently of the preparation method, for cluster cations of aliphatic amino acids, the
protonated form M n H+ is always the dominant species. This is a surprising fact considering …

Mass spectrometry is of paramount importance in many studies of pristine and doped helium
droplets. Here, we attempt to review the body of work that has been performed in this field …
