The region of the nuclear chart around neutron-rich A~100 nuclei is one where prolate and oblate nuclear shapes are predicted to be in close competition. An indirect measurement of the shape of the nucleus can be obtained from measuring level lifetimes which relate, via transition rates, to beta_2 deformation. In order to make measurements of level lifetimes in the sub nanosecond range an...
The African LaBr Array (ALBA) consists of 21 large volume LaBr3:Ce. The characteristics of these crystals, such as the good energy resolution and the high efficiency, make this array very useful for the detection of high-energy gamma rays. The ALBA project foresees the use of the gamma spectrometer in stand-alone mode and coupled to the K600 spectrometer or to silicon-detector arrays for the...
The number of stable isotopes of samarium (Sm), makes this isotopic chain interesting to study at stable ion beam facilities. The scissors resonance (SR) of 151Sm was studied with the aim of understanding the evolution of the SR along the Sm isotopic chain. Change in deformation of a nucleus as it transitions from prolate through spherical to oblate, leads to changes in statistical properties...
In the 1970s and 80s (p, γ) reactions were successfully utilized to measure the photon strength function (PSF) using the Average Resonance Capture Method [1] and this work seeks to explore these reactions to measure the PSF using the ratio and X2 method [2]. The 50Cr(p, γ)51Mn capture reaction has been used to study primary γ-ray transitions from the entry states between the proton and neutron...
