The Hoyle state, second excited state of 12C at an excitation energy of 7.65 MeV, plays an important role in nucleosynthesis. Particularly the radiative decay of the Hoyle state is the doorway to the production of heavier elements in stellar environment. An exclusive experiment has been performed to measure the radiative decay width of the Hoyle state of 12C through the 12C(p, pγγ)12C reaction...
Nuclear theories often operate under the assumption that the strong nuclear force is independent of electric charge. Therefore, it is expected that exchanging the number of protons with the number of neutrons in a nucleus will produce a
The DEcay Spectroscopy (DESPEC) collaboration aims at measuring exotic nuclei produced via fragmentation and fission reactions at GSI/FAIR. In the DESPEC experiments, ions will be stopped in an active implanter and their subsequent decays measured. The active implanter’s role is to provide implantation times and positions and then detect the times and positions of subsequent decaying particles...
Heavy-ion fusion reaction is powerful in expanding the chart of nuclides and exploring the nuclear structure beyond Pb, especailly for high excited states.
The formation of Evaporation Residues (ERs) is governed by three terms: transmission coefficient to overcome the potential barrier, formation probability of Compound Nucleus (CN) and the survival probability of CN against fission. The...
Large-scale computations of fission properties play a crucial role in nuclear reaction network calculations simulating rapid neutron-capture process (r-process) nucleosynthesis. Due to the large number of fissioning nuclei contributing to the r-process, a description of particle-induced fission reactions is computationally challenging. In this contribution, we will use the experimental data on...
In recent times, it is quite complex to determine various nuclear characteristics, e.g., shape, mass, quadrupole (
Tin (Sn),with its magic proton number Z=50, stands out in the periodic table for having the most stable isotopes. This rich array of isotopes makes Tin an ideal candidate for testing theoretical models aimed at describing the effective nuclear force. The singly-magic nucleus Sn-114, with N=64, is situated in the neutron mid-shell between the N=50 and N=82 magic numbers. Tin isotopes that are...
Several works focused on light isotopes [1,2,3] have shown a reduction of the cross sections with respect to the theoretical predictions for single-nucleon knockout reactions. These studies have reached different conclusions regarding the dependence of the reduction factor observed of the spectroscopic factor with respect to the N/Z of the projectile. The study of (p,pX) knockout reactions...
The study of neutron unbound systems via the invariant mass technique is the primary focus of the MoNA Collaboration, which built and operates the Modular Neutron Array (MoNA) and the Large multi-Institutional Scintillator Array (LISA) at FRIB. Advancements in nuclear structure from theory and experiment along the neutron dripline have presented opportunities to understand the nature of...
Accurately characterizing the behaviour of collective states within the context of the shell model and capturing how this feature evolves throughout the chart of nuclides are ubiquitous objectives in the field of nuclear structure. This initiative continues to present as extraordinarily non-trivial when considering regions of heavy nuclei, as such nuclei are highly unique many-body systems...
Nowadays, the study of exotic nuclei is an active area of research, from both experimental and theoretical perspective. Due to low binding energies, exotic nuclei are weakly bound and as a result can break up very easily. This makes it interesting to study their nuclear structure. Our goal in this work is to contribute towards better understanding of the breakup process and its effect on other...
The structure of nuclei around and above the N=50 shell closure provides insight into the interplay between single-particle and collective excitations in neutron-rich nuclei. As one adds neutrons above the N=50 shell closure, nuclei are observed to undergo a rapid change from single-particle excitations into collective modes around neutron number 60. Single-neutron transfer information on...
Exotic nuclei are transforming our understanding of the nuclear force, one manifestation of which is seen in nuclear shells. The conventional nuclear shell model fails to explain the exotic structures seen in nuclei far from stability. In this experiment we examine the exotic borromean nucleus
The production of rare isotopes through projectile fragmentation often relies on reaction mechanism models like the abrasion-ablation model \cite{Campi_81} in simulation codes such as \texttt{LISE}
To probe the frontiers of knowledge on the short-lived isotopes near the neutron drip line for understanding their reactions of astrophysical significance, or hitherto unknown features of nuclear shell structure, one requires novel instrumentation. The IRIS facility features solid hydrogen and deuterium targets, yielding high areal density while remaining geometrically thin (50-100 μm),...
