“…The method is based on an accurate measurement of the Gamow-Teller strength distribution, B(GT), as a function of excitation energy in the daughter nucleus, and relies on the technique of Total Absorption gamma Spectroscopy (TAgS) which will be explained later. The theoretical idea was suggested by Hamamoto et al [11] and pursued by Sarriguren et al [12]. According to them, one can study the deformation of the ground state of a particular nucleus by measuring the B(GT) distribution of its β-decay.…”

A novel method of deducing the deformation of the N=Z nucleus 76 Sr is presented. It is based on the comparison of the experimental Gamow-Teller strength distribution B(GT) from its β-decay with the results of QRPA calculations. This method confirms previous indications of the strong prolate deformation of this nucleus in a totally independent way. The measurement has been carried out with a large Total Absorption gamma Spectrometer, "Lucrecia", newly installed at CERN-ISOLDE.PACS numbers: 21.10. Pc, 23.40.Hc, 27.50.+e, 29.30.Kv, 29.40.Mc The shape of the atomic nucleus is conceptually one of the simplest of its macroscopic properties to visualise. However, it turns out to be one of the more difficult properties to measure. In general terms we now have a picture of how the nuclear shape varies across the Segrè Chart. Nuclei near to the closed shells are spherical. In contrast nuclei with the valence nucleons in between two shells have deformed shapes with axial symmetry and the extent of the quadrupole deformation is quite well described as being proportional to the product N p N n of the numbers of pairs of valence protons (N p ) and neutrons (N n ) [1]. This picture is underpinned by both the Shell and Mean Field models of nuclear structure. Experiment and theory concur that, as the N p N n parameterisation would suggest, nuclei rapidly deform as we add only a small number of valence nucleons to the magic numbers. Thus nuclei in the middle of the f 7/2 shell turn out to be deformed even although the numbers of valence nucleons are relatively small.Experimentally this picture is supported by a mass of independent observations: the strongly enhanced quadrupole transition rates between low-lying states, the strongly developed rotational bands built on low-lying states, and measurements of ground state quadrupole moments. Where we have evidence of the shapes of ground and excited states in the same nucleus they are, in general but not always, the same. It turns out that in some cases nuclear states with different shapes co-exist in the same nucleus [2].The nuclei with N≈Z and A≈70-80 are of particular interest in this context. Such nuclei enjoy a particular symmetry since the neutrons and protons are filling the same orbits. This, and the low single-particle level density, lead to rapid changes in deformation with the addition or subtraction of only a few nucleons. In terms of Mean Field models these rapid changes arise because of the proximity in energy of large energy gaps for protons and neutrons at Z,N=34 and 36 on the oblate and Z,N=38 on the prolate side of the Nilsson diagram. As a result Mean Field calculations predict the existence of several energy minima with quite different shapes in some of these nuclei [3,4]. Evidence of this co-existence has been found for instance in Se and Kr nuclei [5,6], and it is also predicted for the lightest Sr isotopes [7]. Thus it is of considerable interest to map out the deformation of the ground and excited states of nuclei in this region. This is easier said than do...

“…Duration of therapy for these patients is less well defined. 1,8, 9 Currently, there is very limited information concerning the use of aztreonam in the treatment of P. multocida infections. An exhaustive literature review found only 3 in vitro studies testing aztreonam against P. multocida isolates, all of which were inhibited by aztreonam.…”
