The Botswana International University of Science and Technology (BIUST) is a young institution, having opened its doors to the first cohort of students in year 2012. Nuclear Physics research at BIUST is at its infancy. Naturally, we aim to develop human resources capacity through postgraduate research. We, therefore, are always eager to partner and collaborate with researchers from anywhere across the globe. In this presentation I will give an overview of BIUST and research currently ongoing or envisaged in our Nuclear Physics research group. In terms of fundamental nuclear physics research, my main focus will be on the phenomenon of fine structure of the Isoscalar Giant Quadrupole Resonance (ISGQR). This has been studied with high energy-resolution proton inelastic scattering at iThemba LABS, in the chain of stable even-mass Nd isotopes covering the transition from spherical to deformed ground states. A wavelet analysis of the background-subtracted spectra in the deformed 146,148,150Nd isotopes reveals characteristic scales in correspondence with scales obtained from a Skyrme RPA calculation using the SVmas10 parameterization. A semblance analysis shows that these scales arise from the energy shift between the main fragments of the K = 0, K = 1 and K = 2 components.
