Motivation
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 gamma-ray spectroscopy techniques at the thermal neutron energy range, conducted at the PLF (Pelletron Linac Facility) at TIFR, Mumbai.
