The positron decay partial half-lives of [sup 143]Pm and [sup 144]Pm are needed to assess the viability of elemental Pm as a cosmic-ray clock. We have conducted experiments to measure the [beta][sup +] branches of these isotopes; we find [beta][sup +

A low-energy coexisting band Jpi (Ex keV) 0(+) (1182), 2(+) (1418), 4(+) (1701) is identified in the deformed nucleus, 154Gd. Detailed gamma-ray spectroscopy following the beta decays of 154Eu (J=3), (g,m(1),m(2))154Tb (J=0,3,7) is used to establish

High charge states, up to fully stripped 11C and 14O ion, beams have been produced with the electron cyclotron resonance ion sources (LBNL ECR and AECR-U) at Lawrence Berkeley National Laboratory. The radioactive atoms of 11C and 14O were collected i

The authors have studied the beta -spectrum of 14C using a germanium detector containing a crystal with 14C dissolved in it. They find a feature in the beta -spectrum 17 keV below the endpoint which can be explained by the hypothesis that there is a

Analysing powers of the l tr = 0, 31 P( d , 3 He) 30 Si , reaction and its inverse reaction have been measured. Quantities which are proportional to the entrance and exit-channel spin-orbit distortions have been constructed from these analysing power
