Zeptosecond to attosecond dynamics in atoms and possibility of generating a zeptosecond light source
T. Nandi, Soumya Chatterjee, Adya P. Mishra +3
In nuclear collisions, nuclear bremsstrahlung can cause nuclear Coulomb excitation via photon exchange in the projectile as well as the target nuclei. Such a process originating in…
Towards full understanding the physics of heavy ion induced inner shell ionization
Manpreet Kaur, Soumya Chatterjee, T. Nandi
The complex physics of inner shell ionization of target atoms by heavy ion impact has remained only partially solved for decades. Recently, agreement between theory and experiment…
Bremsstrahlung induced atomic processes
Shashank Singh, Narendra Kumar, Soumya Chatterjee +6
The observed spectra in the collisions of neon (Ne) projectiles of 1.8 and 2.1 MeV with an aluminum target (Al) have been successfully segregated from strong bremsstrahlung backgro…
Study of ion induced Inner Shell Ionization cross section through electron capture mechanism
Sumana Ghosh, Debasis Mitra, Soumya Chatterjee
Electron Capture (EC) cross-section from K, L and M shells of the target atoms to the vacant K, L and M shells of the projectile ions have been calculated by deriving the accurate…
Theoretical studies on multiple ionisation and electron capture processes in heavy ion induced M-shell ionisation
Soumya Chatterjee, Sumana Ghosh, D. Mitra
Multiple ionisation and electron capture are found to be vital mechanisms for K and L x-ray emissions along with the direct coulomb ionisation in heavy ion-atom collisions. Natural…
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…
Study of bremsstrahlung radiation coming from a transmission type x-ray generator and its application on EDXRF technique
Soumya Chatterjee, Sumana Ghosh, D. Mitra
We have demonstrated the use of the bremsstrahlung radiation in energy dispersive x-ray fluorescence technique as a tool to perform non-destructive elemental analysis of solid samp…
