TL;DR: A 4 π multi-detector gamma-ray spectrometer named the Indian National Gamma Array (INGA) has been set up at the Inter University Accelerator Centre, New Delhi, for nuclear structure studies as discussed by the authors.

TL;DR: In this paper, the authors used the Coupled Channel formalism to theoretically explain the observed sub-barrier fusion cross-section enhancement, which could not be explained by coupling to inelastic states alone.

TL;DR: In this paper, an optical model (OM) analysis of the quasi-elastic scattering data was carried out, and the fusion cross sections were derived at these energies by subtraction of the integrated transfer cross sections from the reaction cross sections obtained from the fits to quasielastic-scattering data.

TL;DR: Hybrid recoil mass analyzer (HYRA) as discussed by the authors is a dual-mode spectrometer designed to carry out nuclear reaction and structure studies in heavy and medium-mass nuclei using gas-filled and vacuum modes, respectively and has the potential to address newer domains in nuclear physics accessible using high energy, heavy-ion beams from superconducting LINAC accelerator and ECR-based high current injector system.

TL;DR: In this paper, the authors measured evaporation residue (ER) cross sections at beam energies in the range of 101-137.3 MeV and showed that an excitation energy dependent scaling of the finite-range rotating liquid drop model fission barrier is necessary to fit the experimental data.
