Abstract :
The 8He+208Pb reaction was studied in the first experiment with the EXOGAM germanium detector array using beam delivered by the SPIRAL facility. γ-rays from direct and fusion–evaporation reactions were observed with high resolution. γ–γ coincidence data were obtained at a beam intensity level of 105 8He particles per second. Specially designed absorbers and beam detectors could further reduce the background radiation by orders of magnitude.
