Title
Measurements of fission fragment mass distribution after neutron emission using fast neutrons.
Reaction Mechanism
Facility Used in the experiment
At GANIL, I actively contributed to an experiment at the FALSTAFF facility, focusing on actinide fission in the fast-neutron energy domain. I accomplished the following tasks:
- identifying \gamma-peaks,
- converting the time-of-flight (TOF) spectrum to neutron energy spectrum,
- generating spectra for velocity, energy, and mass distribution of fission fragments, and
- determining the efficiency of the Ionization Chamber through GEANT4 simulation.

Title
Nuclear structure studies of the ^{29}P nuclei.
At SINPL, my contribution was extensive in analyzing the gamma spectroscopy data obtained from an experiment conducted at the Variable Energy Cyclotron Center (VECC) in India. 29P nuclei were populated through the natSi(p, γ)29P reaction, utilizing a 10 MeV beam from the Cyclotron.
Reaction Mechanism
Facility Used in the experiment
At SINP, Kolkata, I delved into gamma-ray spectroscopy of excited states of the ^{29}P nucleus, exhibiting the data analysis, including
- data calibration,
- constructing a matrix for gamma-gamma coincidence,
- obtaining gated spectra, and
- identifying several new gamma peaks in ^{29}P.

Reaction Mechanism
Formulae Used to Measure ER Cross-Section
My doctoral research focused on experimental measurements of Evaporation Residue (ER) excitation functions in the 48Ti + 142,150Nd, 144Sm systems. Utilizing the gas-filled mode of the HYbrid Recoil mass Analyzer (HYRA) facility at the Inter-University Accelerator Center (IUAC), Delhi, I conducted detailed studies on proton shell closure and deformation effects. My experience extends beyond this, encompassing diverse experiments such as mass-energy and angular distribution of fission fragments, quasi-elastic scattering measurements, and charged particle and neutron multiplicity measurements.
