We have used the 4 pi BaF2 gamma-ray detector array at the n_TOF neutron time-of-flight facility at CERN for an experiment in order to determine the spins of resonances of n+Sr-87 by measuring the gamma-ray spectra and multiplicity distributions. The first results are presented here. We have assigned the orbital momentum l to all evaluated resonances on the basis of their neutron widths. Further we have assigned the spin J to 16 s-wave resonances on based the population of low-lying levels.

Abstract
We have used the 4 pi BaF2 gamma-ray detector array at the n_TOF neutron time-of-flight facility at CERN for an experiment in order to determine the spins of resonances of n+Sr-87 by measuring the gamma-ray spectra and multiplicity distributions. The first results are presented here. We have assigned the orbital momentum l to all evaluated resonances on the basis of their neutron widths. Further we have assigned the spin J to 16 s-wave resonances on based the population of low-lying levels.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
