Astrophysical ices are exposed to different radiation fields including photons, electrons and
ions. The latter stem from interstellar cosmic rays (CR), the solar and stellar winds, shock …

We studied the effects produced by the interaction of heavy ion cosmic rays with interstellar
and cometary organic molecules in the solid phase. Formic acid (HCOOH) ice at 15 K was …

Methanol is an important precursor of many complex prebiotic species and is found
abundantly, in solid phase, in several astrophysical environments, such as comets and …

In this work, the fragmentation, survival, and chemical reactions of formic acid (HCOOH)
molecules condensed at 56 K are analyzed using plasma desorption mass spectrometry …

Ices are the dominant surface material of many Solar system objects, such as comets and
trans-Neptunian objects. They are continuously exposed to ion bombardment by solar wind …

Recent experimental results on positive charged formic acid clusters generated by the
impact of 252Cf fission fragments (FF) on icy formic acid target are examined in this paper by …

In cold core of dark molecular clouds, where the UV radiation from external sources is
strongly attenuated, cosmic rays can induce chemical reactions on the surface of ice …

Photon stimulated ion desorption (PSID) studies have been performed in condensed formic
acid using oxygen 1s-edge synchrotron radiation from the Brazilian synchrotron light source …

Recent experimental results on negatively charged formic acid clusters generated by the
impact of 252Cf fission fragments on icy formic acid target are compared to quantum …

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 …
