Abstract

Excited energy states totalling 11 in number identified to be associated with the 42Ca were detected via the ROSPHERE gamma-ray array detectors of IFIN-HH Bucharest from a 28Si(18O, 2p2n), where a multi-particle of 2 protons and 2 neutrons were evaporated in a fusion reaction. The excited energies were identified using ?-ray coincidences. All detected gamma energies (?) recorded were compared with various literatures from NNDC and this shows an excellent agreement with each and the results are presented together with their calculated relative intensities.
