- Abstract
From new measurements, a half-live of 4.2±0.3 s has been clearly established in
127 Pr. This value confirms our first result [4] and rules out other data [5]. The127 Pr activity was produced by bombarding92 Mo or94 Mo targets with 210 MeV40 Ca beams. The mass identification has been made using an ion-guide coupled with an on-line isotope separator. The partial level scheme proposed for127 Ce has been deduced from ß-gated ? spectra and X?- and ??-coincidences. A new band structure based on a 1/2+ state is established.- Published
