In 2006, a final result of a measurement of the gravi- tational constant G performed by researchers at the University of Zürich, Switzerland, was published. A value of G=6.674252(122)×10

High quality epitaxial Co and Fe silicides have been grown by molecular beam epitaxy on Si(111) and Si(001) substrates with film thicknesses ranging between 25 and 8400 A. We used Rutherford backscattering spectrometry channeling techniques to measur

The gamma-decay of the 4.46- and 5.03-Mev levels of B/sup 11/ was determined by (p, gamma ) coincidences using the reaction Be/sup 9/(He/sup 3/,p)B/ sup 11/. The 5.03-Mev level decays with a probability of 0.14 plus or minus 0.03 via the state at 2.1

The energy levels in ${\mathrm{B}}^{10}$ at 4.77 and 5.16 MeV have been studied by means of the reactions ${\mathrm{B}}^{11}({\mathrm{He}}^{3},\ensuremath{\alpha}){\mathrm{B}}^{10}$ and ${\mathrm{Li}}^{6}(\ensuremath{\alpha},\ensuremath{\gamma}){\mat

The status of the possible E1-E3 cascade between the 2 + state at 6.92 mev, the 3- state at 6.14 mev and the 0+ ground state of 16O is reviewed in the light of recent improvements in our knowledge of radiative transitions and isotopic spin impurities

The positron-electron pair-line spectrum of the 2.13-MeV transition in ${\mathrm{B}}^{11}$ has been measured by means of an intermediate-image pair spectrometer using the reaction ${\mathrm{B}}^{11}(p,{p}^{\ensuremath{'}}){\mathrm{B}}^{11*}$ at the 2

The degree to which parity is conserved in strong inter actions was studied and F/sup 2/, the intensity of the component determined. A thick target of TiN/sup 15/ was irradiated with a beam of deuterons at 1.1 Mev. The consequent N/sup 16/ decay was

The angular distribution of neutrons from the reaction N/sup 14/(d,n)O/ sup 15/ (g.s.) was measured at 8 bombarding energies between 1.35 and 2.8 Mev. The same measurements were made on the neutron groups (unresolved) from the reactions N/sup 14/(d,n
