310 MevPi+−pPolarization and Cross-Section Experiments. Phase-Shift Analysis

Autor: Owen Chamberlain, Ernest H. Rogers, Thomas Ypsilantis, James H. Foote, Herbert M. Steiner, Clyde Wiegand

Publikováno v: Reviews of Modern Physics. 33:356-361

The cross sections and proton polarizations in pi +-p interactions st 310 Mev are measured, in an attempt to find an unambiguous set of SP, SPD, or SPDF phase shifts for the system. The experimental data can be made to fit unambiguously a given set o

π+−pElastic Scattering at 310 Mev: Recoil-Nucleon Polarization

Autor: Owen Chamberlain, Ernest H. Rogers, Herbert M. Steiner, James H. Foote, Thomas Ypsilantis, Clyde Wiegand

Publikováno v: Physical Review. 122:948-958

The recoil-proton polarization in {pi}{sup +}-p elastic scattering at 310-Mev incident-pion laboratory kinetic energy has been experimentally measured at four scattering angles with scintillation counters. Polarization values obtained, related rms ex

Search for a neutral meson of zero I-spin

Autor: Owen Chamberlain, Ernest H. Rogers, Norman E. Booth

Publikováno v: Il Nuovo Cimento. 19:853-863

A search has been made for a neutral meson of zero I-spin by means of the reaction d+d→4He+π00. No evidence was found for the existence of the π00 in the mass range zero to 1.8 times the π± mass. The upper limit of the cross section was 7·10�

Meson Production inp+dCollisions and theI=0π−πInteraction. I. Measured Momentum Spectra ofHe3andH3Nuclei from High-Energyp+dCollisions

Autor: Norman E. Booth, Alexander Abashian, Ernest H. Rogers, Roger E. Hill, Kenneth M. Crowe

Publikováno v: Physical Review. 132:2296-2304

The momentum spectra of ${\mathrm{He}}^{3}$ and ${\mathrm{H}}^{3}$ nuclei produced in $p+d$ collisions have been measured with high resolution. Data were obtained at several angles and incident proton energies of about 745 MeV. Each spectrum exhibits

π+−pScattering and Phase-Shift Analysis at 310 Mev

Autor: Thomas Ypsilantis, Clyde Wiegand, Owen Chamberlain, Ernest H. Rogers, Herbert M. Steiner, James H. Foote

Publikováno v: Physical Review Letters. 4:30-33

At the 184-inch synchrocyclotron in Berkeley, data were obtained on elastic pi /sup +/-scattering at 310 Mev. Quantities measured were the differential cross section, the total cross section, and the polarization of the recoil protons as a function o

Experiments on Antiprotons: Cross Sections of Complex Nuclei

Autor: Lewis E. Agnew, Clyde Wiegand, Owen Chamberlain, Ronald Mermod, Donald V. Keller, Ernest H. Rogers, Herbert M. Steiner

Publikováno v: Agnew, Jr., Lewis E.; Chamberlain, Owen; Keller, Donald V.; Mermod, Ronald; Rogers, Ernest H.; Steiner, Herbert M.; et al.(1957). Experiments on Antiprotons: Cross Sections of Complex Nuclei. Lawrence Berkeley National Laboratory. Lawrence Berkeley National Laboratory: Lawrence Berkeley National Laboratory. Retrieved from: http://www.escholarship.org/uc/item/8kt548s4

Experiments are described that have been designed to measure separately annihilation and reaction cross sections for antiprotons of approximately 450 MeV on oxygen, copper, silver, and lead. A new and more luminous spectrograph has been built for thi

Publikováno v: Solar Physics. 13:57-77

Time-lapse photographs of the Hα chromospheric network were taken at 3-sec intervals with a$\tfrac{1}{4}$-A filter centered at Hα + 0.65 A, where the network appears as a system of dark mottles. A nearly continuous sequence of 62 hr duration was

Auroral photography from a satellite

Autor: Ernest H. Rogers, Richard C. Savage, David F. Nelson

Publikováno v: Science (New York, N.Y.). 183(4128)

Photographs taken from satellites show the form, location, and intensity of the aurora from a new perspective. They provide an effective way of monitoring auroral activity on a worldwide basis and are likely to become one of the major tools in the ef
