Ionization-Driven Dehydrogenation and Molecular Growth in Gas-Phase Adamantane Clusters

Sumit Srivastav, Per Eng-Johnsson, Raimund Feifel +4

We investigate fragmentation and molecular growth induced by keV ions in initially neutral gas-phase adamantane clusters, the simplest diamondoid molecule (Ad, C $_{10}$ H $_{16}$ ). U…

Direct evidence for projectile electronic structure effects in slow multielectron capture collisions

Akash Srivastav, Sumit Srivastav, Bhas Bapat

We investigate the role of the electronic structure of the projectile in ionization and subsequent fragmentation of CO $_{2}$ induced by multielectron capture in collisions at 0.31 a.…

Association between projectile and target excitation in slow Ar $^{q +}$ -CO $_{2}$ collisions

Akash Srivastav, Sumit Srivastav, Vishnu P +1

We investigate ionic fragmentation of CO $_{2}^{n +}$ ~\mbox{( $2 \leq n \leq 4$ )} produced in collisions with Ar $^{q +}$ ~\mbox{( $4 \leq q \leq 16$ )} projectiles at a collision velocity of $\appr…

Electron capture induced fragmentation of CO $_{2}^{3 +}$ : Influence of projectile charge on sequential and concerted break-up pathways

Akash Srivastav, Sumit Srivastav, Bhas Bapat

We investigate the $O^{+} : C^{+} : O^{+}$ fragmentation channel of CO $_{2}^{3 +}$ produced in slow collisions with Ar $^{q +}$ projectiles ( $4 \leq q \leq 16$ , velocities $\ap…

Isomer effects on neutral-loss dissociation channels of nitrogen-substituted PAH dications

Sumit Srivastav, Sylvain Maclot, Alicja Domaracka +2

We investigate two nitrogen-containing isomers of polycyclic aromatic hydrocarbons (PAHs), quinoline (Q) and isoquinoline (IQ), of composition C $_{9}$ H $_{7}$ N in collisions with 7~keV…
