Thin layer activation analysis (TLA) technique using a high energy ion beam is a nuclear technique for measurement of surface loss of materials in the micrometer range. It has been widely used to measure wear, corrosion or erosion in automobile industry, power plants, process industry, oil and petroleum refineries and in many high technology areas. In the proposed study the application of TLA meth

Our foundational hypothesis is predicated upon the notion that the deliberate bombardment of these specified nanomaterials with a selection of ionic species will catalyze the genesis of bifurcated defect modalities: i) vacancies, and ii) adatoms (doping), or a sophisticated amalgamation of both, contingent upon the interplay between the ion's type and its kinetic energy dynamics. The strategic inc

The study of breakup-fusion mainly focuses on weakly-bound projectiles with breakup thresholds 1.45--2.45MeV. However, 10B also has low α-separation energy (4.5MeV), suggesting it may undergo breakup and significantly impact fusion mechanisms at low energies. Measurements from 10,11B+159Tb/209Bi showed complete fusion suppression of ~15% for 10B and 7% for 11B reactions above the barrier. Since t

Following its discovery, numerous theoretical and experimental endeavors have been undertaken to unravel the microscopic structure of the Pygmy Dipole Resonance (PDR). However, despite these efforts, several unresolved questions persist, impeding a systematic understanding of the underlying microscopic structures of the PDR. These inquiries include whether there exists an onset of single-particle

We found that there is a scope to identify the new isotopes for Bk which has half-lives greater than 10-6s. Our theoretical calculation (see Appendix IV) predicts that the next heavy nuclei with Z=97, N=139 (A=236, T1/2=0.933s (β-decay)) can be synthesized with a good residual cross-section of 87pb by the target of 209Bi and projectile of 30Si at about 147.53 MeV.

We have recently conducted measurements on quasi-elastic scattering using 16,18O projectiles directed at 90Zr nuclei at energies near the Coulomb barrier. Our findings
reveal notable discrepancies between the data obtained for 18O and 16O, suggesting a distinct involvement of di-neutron transfer in the fusion process of 18O with 90Zr.
Specifically, the fusion barrier distribution for 18O+90Zr ex

In a decade since the discovery of asymmetric split in β-delayed fission of 180Tl the fission of the preactinides has witnessed considerable development both theoretically as well as experimentally. We had an ongoing experimental program to systematically explore the new kind of asymmetric fission observed in the preactinide region. In this regard we intend to measure fission fragment mass and TK

This PhD thesis proposal aims to undertake experimental investigation on octupole correlation of the nucleus of mass number A~60-70 region. For this purpose, We select
68Zn and 70Ge and their close by neighbors. The systematic study of some parameters will help to explore the collective behavior of the proposed nuclei and its neighbour.

Neutron capture plays a crucial role in nucleosynthesis in massive stars (M/M₀ ⩾8), where most isotopes from Fe to Sr are created through neutron capture reactions. However, significant disparities exist in the literature regarding the neutron capture cross sections of 63Cu(n,γ)64Cu and 65Cu(n,γ)66Cu. This proposal aims to investigate these cross-sections using neutron activation and offline

The exotic phenomenon of two-phonon gamma-vibration in deformed nuclei has been a stimulating and extensively discussed theme in nuclear structure research. The Erbium isotopes offer a unique opportunity to experimentally observe such exotic collective excitations, and test alternative theoretical model approaches.

investigate the lifetime of (13/2)^+ isomeric state in 205At which is unknown. In addition to that, as the study associated with 205At is very old, a scope for re-investigation is there to justify the old lifetime values for other isomeric states as well in 205At. Also, for the 207At, we c

The discrepancy with stellar abundance of Sn isotopes still remains. In this respect, measurements of (p,γ) cross sections on proton rich Sn isotopes gives insight into the (γ,p) cross sections and implicitly into the dilemma involving the p-process contribution to the formation of these nuclei. Extending measurements to proton capture cross sections on Sn isotopes would provide a higher reliabi

We want to test the PARIS detector using in-beam experiment coupled to INGA. We are using Pixie based DDAQ. Two different crates, one for clover, CsI and other one for PARIS,LaBr3(Ce) detector will be used and will have to be time synchronized.
This improved setup is important to get new insight about the high spin behavior of the isotopes near A = 90.

Recent studies highlight a transition in pre-scission α-particle multiplicity from high to very low values at the Businaro Gallone point during heavy-ion induced fission of 232Th. This behavior, observed across various induced fission reactions, indicates significant dynamical effects in entrance channels suggesting a reversal in mass flow direction, leading to di-nuclear configurations and prem

One of these aspects is nuclear isomers. Study of isomers is very important as they provide testing ground to variou

The experimental nuclear measurements are needed to validate as well as to get the appropriate data set which can complete the data for entire energy range for future nuclear reactor application. The current proposal, as part of my PH.D, aims for taking results of the systematic activation cross section for few pre-decided isotopes, for which the available nuclear data is discrepant.
