    Beta-delayed proton precursors with 59≦Z≦62 (1985)

    Notes: Abstract The new, beta-delayed proton emitters128Pr(3.2 −0.4 +0.5 s),130Pm(2.2 −0.4 +0.6 s), and132Pm(5.0 −0.6 +0.8 s) have been observed at the on-line isotope separator OASIS. Also studied were129Nd and133Sm. Our on-going study of the decay properties of very neutron-deficient lanthanides has led to detailed information about beta-delayed proton emitters with 59≤Z≤62. The isotopes were produced at the SuperHILAC's on-line isotope separator OASIS [1] in reactions of40Ca projectiles on92Mo and96Ru targets enriched to 〉95%. Decay studies were carried out in a low background spectroscopy laboratory. The isotope of interest was passed through a slit in the focal plane of the mass separator, transported ionoptically to a fast cycling tape, and periodically positioned between a silicon charged particle telescope, a HPGe x-ray detector, and a GAMMA-X Ge detector. Decays involving beta-delayed gamma rays and protons along with any coincident positrons, x-rays and gamma rays were measured event-by-event and written to computer tape for subsequent replay and analysis.

    Beta-delayed proton emission in the lanthanide region (1986)
    Springer
    The European physical journal 325 (1986), S. 485-486

    Notes: Abstract Several new β-delayedproton precursors were produced in (HI; xn, yp) reactions at the LBL SuperHILAC and studied with the isotope separator OASIS. Unambiguous Z-identifications were obtained in all cases by observing characteristic x-rays coincident with the protons. Ground state spins were determined in favorable cases. The lowest 2+ levels in the rotational bands of126Ce and130Nd were confirmed.

    Identification of the neutron-rich isotope174Er (1989)

    Notes: Abstract The heaviest known erbium isotope, 3.3(2) min.174Er, has been identified using on- line isotope separation and by ß and γ- ray spectroscopy. Twelve γ rays were placed in a preliminary decay scheme. The mass of the new isotope was established by the separator and the Z was deduced from Tm K x ray coincident ß and γ rays. In addition, the heaviest known isotope of holmium171Ho was observed with a half-life of 49(5) s.

    A New Gamma-Ray Spectrum Catalog for PGAA (2000)
    Springer

    Notes: Abstract A major obstacle to the use of the prompt gamma activation analysis (PGAA) method has so far been the lack of a suitable library. Therefore, new measurements have been performed at the PGAA facility at Budapest Research Reactor (BRR) in order to create a prompt γ-ray catalog for qualitative and quantitative analysis. Prompt γ-ray energies and associated k 0-factors have been determined by internal standardization. The resulting catalog contains prompt γ-ray data from neutron capture and other reactions such as (n,α), and decay γ-ray data from short-lived reaction products. Data have been measured for nearly all stable elements, from hydrogen to uranium. Generally, data for several isotopes are given, to enable isotopic analysis as well.
