Level scheme of /sup 148/Pm and the s-process neutron density
Journal Article
·
· Phys. Rev. C; (United States)
A level scheme of /sup 148/Pm up to 800 keV is deduced from gamma-ray coincidence data and published particle transfer data. Approximately 106 gamma-ray transitions have been placed between 36 levels. We have identified three levels below 500 keV in excitation which decay to both the ground state and to the isomeric level at 137 keV. The presence of these levels guarantees that /sup 148/Pm/sup g//sup ,//sup m/ are in thermal equilibrium during the s process. The s-process neutron density inferred from the branch point at /sup 148/Pm is deduced to be 3 x 10/sup 8//cm/sup 3/.
