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 γ-ray coincidences. All detected gamma energies (γ) 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.

Highlights

The particle of 2n2p was evaporated from the fusion of 28Si target measured gamma energies of the nucleus have been reported in with 18O – beam. 28Si was found to be one of the impurities several articles with some of them showing the relative inten- in the 192Os target foil material bought from the Trace company sities of the measured gamma transitions
The experiment for the 18O beam on 192Os target was conducted for a period of 9 consecutive days at IFIN-HH Bucharest within which an approximate count of 1,200,000.00 was recorded using the ROmanian SPectroscopy in HEavy REactions, ROSPHERE gamma-ray array of 14 High Purity Germanium, HPGe and 11 Lathanum-Bromide doped Cerium, LaBr3(Ce) detectors [4, 5, 6]
Coincidence analysis was performed on the detected gamma energies from the ROPSHERE gamma-ray array detectors of the IFIN-HH Bucharest and these were identified to be associated with 42Ca

Summary

Experimental Details

The particle of 2n2p was evaporated from the fusion of 28Si target measured gamma energies of the nucleus have been reported in with 18O – beam. This contaminated percentage of 42Ca and other chemintensities of these gamma energies have been measured after ical impurities from the target were observed to have reacted they were identified to be associated with 42Ca through the in- during the experiment when the 18O beam delivered the laborastrumentalities of Coincidence analysis [2]. The experiment for the 18O beam on 192Os target was conducted for a period of 9 consecutive days at IFIN-HH Bucharest within which an approximate count of 1,200,000.00 was recorded using the ROmanian SPectroscopy in HEavy REactions, ROSPHERE gamma-ray array of 14 High Purity Germanium, HPGe and 11 Lathanum-Bromide doped Cerium , LaBr3(Ce) detectors [4, 5, 6]
