A new high-spin isomer in 215Bi, with a half-life of 36.9(6) s, has been identified at the PSB-ISOLDE on-line mass separator using the pulsed-release technique combined with the element selective RILIS source. A decay scheme of $^{215{\rm m}}$ Bi was constructed and complemented with the low-spinstructure observed in $^{215{\rm g}}$ Bi decay. The population of a cascade on top of the $\left( \nu g_{9/2} \right)^5_{9/2+}$ level in 215Poprovides evidence for Gamow-Teller $\beta$ -decay of the high-spin 215Bi isomer.Type of Medium: Electronic ResourceURL: -

Exotic, neutron-rich proton-induced spallation products of 232Th and 238U obtained from the PS Booster ISOLDE facility have been investigated by $\gamma$ - $\gamma$ , $\alpha$ - $\gamma$ coincidence and spectrum-multiscaling measurements. A new method for the reduction of isobaric contamination enabled to study the unknown region beyond 208Pb for the decay chain A = 217. A new isotope 217Bi with a half-life of $98.5 \pm 0.8$ s was discovered and its $\beta$ -decay studied. For the first time, a half-life value of $1.53 \pm 0.03$ s for the $\alpha$ -decay of 217Po was measured.Type of Medium: Electronic ResourceURL: -

Published 2003Staff ViewISSN: 1434-601XSource: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract. Beta-decay experiments are a primary source of information for nuclear-structure studies and at the same time complementary to in-beam investigations of nuclei far from stability. Although both types of experiment are mainly based on $\gamma$ -ray spectroscopy, they face different experimental problems. The so-called Pandemonium effect is a critical problem in $\beta$ -decay if we are to test theoretically calculated transition probabilities. In this contribution we will present a solution to this problem using total absorption spectroscopy methods. We will also present some examples of experiments carried out with the Total Absorption Spectrometer (TAS) at GSI an describe a new device LUCRECIA recently installed at CERN.Type of Medium: Electronic ResourceURL: -

A new method for reducing isobaric contamination enabled to cover the unknown region “east” of 208Pb for the isobaric chain A=216. The half-life of the β decay of 216Bi was found as T1/2= 135 ± 5 s.

A beam of 270 MeV58 Ni was used to bombard a 54 Fe target. Reaction channel separation was achieved with a 4π charged particle multi-detector set-up together with a 1π neutron detector wall placed in the forward direction. Gamma-ray transitions belonging to the 111 I nucleus were identified for the first time. A level scheme constructed from γ-γ-particle-coincidence analysis is proposed. The level structure is discussed within the framework of the shell model and the systematics of the heavier odd iodine nuclei.Type of Medium: Electronic ResourceURL: -

ISSN: 1588-2780Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyEnergy, Environment Protection, Nuclear Power EngineeringNotes: Abstract Time evolution of the cumulated activity in human body is one of the key characteristics determining medical impacts of ionizing radiation. In nuclear medicine, so called effective half-life is mostly used for describing the evolution. This quantity is usually estimated by fitting a straight line in semi-logarithmic coordinates. Its novel Bayesian estimate was also proposed and its advantageous properties were verified. During extensive tests, it was found that the effective half-life has limited use as the underlying deterministic relationship time-activity can hardly be taken as (mono)exponential. It stimulated the search for a better and still simple model. A quadratic dependence of ln (activity) on ln (time) was found as an adequate candidate. Preliminary experiments on a restricted set of real data were promising enough to justify its further elaboration. The paper reports on the progress made in verifying and exploiting this non-standard model. Its potential exploitation in dosimetric tasks is outlined. The core of the paper describes a positive verification of our results on an extensive set of real data.Type of Medium: Electronic ResourceURL:
