A liquid-hydrogen target surrounded by spark chambers was used to study ${K}^{+}$-proton elastic scattering at 970, 1170, and 1970 MeV/c incident ${K}^{+}$ momentum. In contrast with results lower energies, the angular distributions were not isotropic; anisotropy increases energy, while cross section decreases. number of phase-shift solutions using (a) ${S}_{\frac{1}{2}}$, ${P}_{\frac{1}{2}}$, ${P}_{\frac{3}{2}}$ complex phase shifts; (b) real ${P}_{\frac{3}{2}}$, ${D}_{\frac{3}{2}}$ (c)...
Measurements have been made of the differential cross sections for ${\ensuremath{\pi}}^{+}p$ and ${\ensuremath{\pi}}^{\ensuremath{-}}p$ elastic scattering at incident beam momenta in range 875 to 1579 MeV/c. Two arrays scintillation counters were used detect pions scattered from a liquid-hydrogen target coincidence with recoiling protons. In each 25 angular distributions, data obtained 18 center-of-mass angles varying ${cos\ensuremath{\theta}}^{*}=\ensuremath{-}0.97$...
The discrepancy in the K/sup +/-p cross section sigma /sub p/, that of obtaining p/= 12,9 plus or minus 1.0 mb at2.4 Bev/c and 24.5 2.5 at 2.9 Bev/c, is explained. Graphical tabular data corrections are given, a diagram apparatus presented. (L.N.N.)
>It is shown that a determination of K LAMBDA N parity may, under certain assumptions, be obtained by measuring the s wave to p amplitudes in decay yields + pi /sup -/. Measurements are reported, and resuits on parameters for decays SIGMA +/ 0/ -/ presented discussed. (L.N.N.)
Ion beams of ${\mathrm{He}}^{+}$ and ${\mathrm{He}}^{++}$, in the kinetic energy range 100 to 450 kev, are held arcs circular orbits a magnetic field. When few microns gas admitted beam is attenuated by charge-changing collisions, since with change charge ion lost from its orbit. Cross sections for such collisions designated ${\ensuremath{\sigma}}_{\mathrm{if}}$, where $i$ initial positive ionic electron units $f$ after collision. (${\ensuremath{\sigma}}_{10}+{\ensuremath{\sigma}}_{12}$) has...

Energy levels of the nucleus ${\mathrm{C}}^{15}$ have been measured by measuring kinetic energies proton groups produced in bombardment thin beryllium targets with 2-Mev lithium ions, causing reaction ${\mathrm{Be}}^{9}({\mathrm{Li}}^{7}, p){\mathrm{C}}^{15}$. The energy found were at 0.62, 2.48, 3.08, 4.26, 5.93, 6.58, and 8.18 Mev above ground state. A continuum particles was interpreted as due partly to pn){\mathrm{C}}^{14}$. state lowest compared ${\mathrm{N}}^{15}$; presence...
If parity is conserved, neutrons produced in the interaction of unpolarized protons with an target should have zero longitudinal component polarization. An experiment described which polarization 350 MeV neutron beam emerging from internal beryllium a synchrocyclotron measured. The result that, if reaction matrix describing production process contains term F(σ.P/P), where σ, P are spin and momentum, then |F|2 ⩽ 3.6 × 10-6 95% confidence.
