Electron Emission Cross Section from Methane under 250 keV Proton Impact
Autor: Debasmita Chakraborty, László Gulyás, Lokesh C. Tribedi
Publikováno v: Atoms. 11:49
We measure double differential cross sections (DDCS) of electrons emitted from CH4 molecules in collisions with 250 keV protons. The projectile ions are obtained from a 400 kV electron cyclotron resonance-based ion accelerator (ECRIA). We study the e

1s-1s electron transfer in collisions of fast C and O ions with adenine
Autor: Gregory Lapicki, Lokesh C. Tribedi, Chandan Bagdia, A. Mandal, M. Roy Chowdhury, Shamik Bhattacharjee
Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 462:68-74
1s-1s electron transfer and K-shell ionization cross sections of adenine (C5H5N5) molecule have been measured in collisions with C and O ions in the energy range of 2.5–5.3 MeV/u. These cross sections have been measured from the study of KLL Auger

A recoil ion momentum spectrometer for probing ionization, e-capture, and capture-ionization induced molecular fragmentation dynamics
Autor: Shubhadeep Biswas, Lokesh C. Tribedi
Publikováno v: The Review of scientific instruments. 92(12)
The development of a recoil ion momentum spectrometer (RIMS) along with a post-collision projectile charge state analyzer (CSA) and its performance for carrying out studies of molecular fragmentation following direct ionization, electron-capture, and

Volume 11
Issue 2
Pages: 21
In low energy ion-molecule collisions, electron capture is one of the most important channels. A new experimental setup was developed to study the electron capture process using low-energy ion beams extracted from an electron cyclotron resonance (ECR
