| dc.description.abstract | Abstract. A program to study the γ -ray decay from the region of high-level density has been established
at iThemba LABS, where a high-resolution gamma-ray detector array is used in conjunction with silicon
particle-telescopes. Results from two recent projects are presented: 1) The 74Ge(α, α
γ ) reaction was used
to investigate the Pygmy Dipole Resonance. The results were compared to (γ,γ
) data and indicate that the
dipole states split into mixed isospin and relatively pure isovector excitations. 2) Data from the 95Mo(d,p)
reaction were used to develop a novel method for the determination of spins for low-lying discrete levels
utilizing statistical γ -ray decay in the vicinity of the neutron separation energy. These results provide insight
into the competition of (γ ,n) and (γ,γ
) reactions and highlights the need to correct for angular momentum
