The 3701 keV Neutron g9/2 Single-particle State in 57Ni

The neutron g(9/2) single-particle state in Ni-57 has been unambiguously identified in a combined measurement of the linear polarization, angular distribution, and angular correlation of gamma rays following the fusion-evaporation reaction Si-28(S-32,2pn)Ni-57 at a beam energy of 90 MeV. The linear polarization was measured with a EUROBALL cluster detector and a prototype of an encapsulated six-fo

Mögelangrepp på fogmassor i våtrum

Så kallade "mjukfogar" förekommer på ett flertal olika ställen i våtrum, t ex vid badkar, dusch, handfat och övrigt sanitetsgods, i kakelbeklädnader i vägghörn och golvvinklar och vid genomföringar. För att undvika problem med mögelangrepp krävs bl a att fogmassan är av rätt typ och fogen ges en lämplig utformning

Transition probabilities for the UV0.01 multiplet in N III

We report on large-scale ah initio multiconfiguration Hartree-Fock calculations for the UV0.01 multiplet, 2s(2)2p(2)P(J)-2s2p(2 4) P-J', in N III. The resulting transition probabilities agree very well with recent semiempirical calculations, and the lifetimes for two of the three upper levels agree with experiments. The deviation for the third level is discussed. Comparisons made with the highest

System för rapporterande utvärdering av kurser vid Lunds tekniska högskola

I detta kapitel beskrivs hur man vid Lunds tekniska högskola organiserar kursvärderingar som en del i ett övergripande arbete med rapporterande utvärdering av kurser. Syftet är att bidra med förståelse för hur olika konkreta problem förknippade med genomförandet av ett system för kursvärdering och utvärdering angripits på Lunds tekniska högskola. kapitlet visar också på hur Lunds tekniska högskola

Radiative lifetimes of GdI and GdII

Natural radiative lifetimes of 25 even-parity levels in Gd i (4f(7) 5d(2) 6p, 4f(7)5d6s6p and 4f(8)5d6s configurations) and 13 even-parity levels in Gd it (4f(7)5d6p and 4f(7)6s6p configurations) have been measured using the time-resolved laser-induced fluorescence technique in a laser-induced gadolinium plasma. The Gd I and Gd it levels range in energy from 26 866 to 36 395 cm(-1), and 25 960 to

Spectroscopic Atlas of Atmoshperic Microwindows in the Middle Infra-Red

This second edition of the infrared microwindow atlas contains a collection of spectral mi- crowindows commonly used or recently suggested for ground-based, high resolution, infrared solar absoption spectroscopy. These solar observations are aimed at quantifying the abun- dance of trace species in the terrestrial atmosphere. A microwindow is a narrow spectral interval that allows to observe a spec

A simple way to extract baddeleyite (ZrO2)

[1] Baddeleyite is a reliable geochronometer for dating the crystallization of mafic and other silica-undersaturated intrusive rocks. Its high U and negligible initial Pb content enable precise age determinations with statistical errors of a few million years or less. The widespread use of baddeleyite for dating has, however, been limited by the low content of baddeleyite in many samples and by di

Asymptotics for sums of random variables with local subexponential behaviour

We study distributions F on [0, infinity) such that for some T less than or equal to infinity F*(2)(x, x + T] similar to 2F(x, x + T]. The case T = infinity corresponds to F being subexponential, and our analysis shows that the properties for T < &INFIN; are, in fact, very similar to this classical case. A parallel theory is developed in the presence of densities. Applications are given to ran

On-line automated sample preparation for liquid chromatography using parallel supported liquid membrane extraction and microporous membrane liquid-liquid extraction

An automated system was developed for analysis of non-polar and polar ionisable compounds at trace levels in natural water. Sample work-up was performed in a flow system using two parallel membrane extraction units. This system was connected on-line to a reversed-phase HPLC system for final determination. One of the membrane units was used for supported liquid membrane (SLM) extraction, which is s
