Zeptosecond dynamics in atoms: fact or fiction?
T. Nandi, Prashant Sharma, Soumya Chatterjee +5
Photon exchange due to nuclear bremsstrahlung during nuclear collisions can cause Coulomb excitation in the projectile and the target nuclei. The corresponding process originated i…
Understanding the L-shell ionization mechanism through osmium atoms bombarded by 4-6 MeV/u fluorine ions
Soumya Chatterjee, Sunil Kumar, Sarvesh Kumar +9
The L-subshell ionization mechanism is studied in an ultra-thin osmium target bombarded by 4-6 MeV/u fluorine ions. Multiple ionization effects in the collisions are considered thr…
Exploring a novel model for projectile charge state distribution inside a solid-target
Soumya Chatterjee, Prashant Sharma, D. Mitra +1
For the first time, we report a theoretical methodology to predict charge state distribution of projectile ions inside a solid-target. The method utilizes either a simple Fermi gas…
Evaluation of accurate uncertainty of measurement in L subshell ionization cross-section
Shashank Singh, Soumya Chatterjee, Debasis Mitra +1
To have a better understanding of a physical process, a comparison of ex-perimental data with theoretical values is mandatory. The comparison ismeaningful if the uncertainty in the…
Significance of high charge state of projectile ions inside the target and its role on electron capture leading to target ionization phenomenon
Soumya Chatterjee, Prashant Sharma, Montanary Claudia +2
The K x-ray spectra of different targets (Cu, Zn, and Ge) induced by 3 to 5 MeV/u Si projectile ions have been measured to determine the K-shell ionization cross-section. A signifi…
