The ^(16)O + ^9Be reactions have been studied from E_(c.m.) = 2.0 MeV to 5.1 MeV, an energy near the top of the Coulomb barrier. The cross section for the neutron transfer reaction ^9Be(^(16)O,^(17)O^∗ (0.87 MeV))^8Be has been measured over this ra

$\ensuremath{\alpha}$-particle yields from the $^{10}\mathrm{B}(n,\ensuremath{\alpha})^{7}\mathrm{Li}$, $^{7}\mathrm{Li}^{*}$ reactions have been measured at eight angles between 0\ifmmode^\circ\else\textdegree\fi{} and 150\ifmmode^\circ\else\textdeg

The ^(14)N+^(10)B fusion reactions were studied at c.m. energies between 2.9 and 7.5 MeV by measuring the yields of γ-rays from the residual nuclei formed by particle evaporation from the compound system. Cross sections for formation of the evaporat

The branching fraction for the isospin-symmetry-hindered positron decay of ^(42)Sc to ^(42)Ca (1.837 MeV) was measured to be (6.3 ± 2.6) × 10^(−5) by observation of delayed γ-rays. This branch alone corresponds to a reduction of the superallowed

Analyzing powers of the /sup 6/Li(n,/sup 3/H)/sup 4/He reaction have been measured at six angles for neutron energies from 0.2 to 1.5 MeV. A supplementary data set at two angles extends the energy range to 2.4 MeV. An energy continuum of neutrons was

Excitation functions for the elastic scattering of protons by ${\mathrm{B}}^{10}$ have been measured at center-of-mass scattering angles near 90\ifmmode^\circ\else\textdegree\fi{}, 125\ifmmode^\circ\else\textdegree\fi{}, and 160\ifmmode^\circ\else\te

Boron concentrations as a function of depth below the surface of a solid of otherwise-known composition may be determined from neutron spectra resulting from the 11B(p,n)11C reaction. Pulsed-beam, time-of-flight techniques have been used to study thi

The resonance at E (19F) =6.42 MeV in the reaction 1H(19F,alphagamma)16O has been explored as a potentially useful method for the quantitative determination of hydrogen concentration as a function of depth in a solid substrate. The relative merits of

The early uses of Scanning Transmission Ion Microscopy (STIM) with MeV ions are reviewed. The transformation of STIM energy-loss images into maps of areal density is discussed, and is illustrated with images of a fruit fly head (Drosophila melanogast
