Abstract
Differential cross-section excitation functions at lab scattering angles 86.9°, 120.0°, 140.0° and 160.0° were measured for 9Be(p, po)9Be, 9Be(p, p2)9Be and 9Be(p, d0)8Be at proton lab energies from 6 to 15 MeV in 100 keV steps. A broad anomaly was observed in the 9Be(p, p0)9Be excitation functions. Differential cross-section angular distributions were measured for 9Be(p, p0)9Be and 9Be(p, p2)9Be at lab energies of 13.0, 14.0, 15.0, 21.35 and 30.3 MeV and for 9Be(p, d0)8Be at 13.0, 14.0, 15.0 and 21.35 MeV. Angular distributions of polarization analysing powers for 9Be(p,p0)9Be, 9Be(p, p2)9Be and 9Be(p, d0)8Be were measured at 8.0, 11.0, 12.0, 13.0 and 15.0 MeV. A spherical optical-model (SOM) analysis of the elastic scattering angular distribution data from 13.0 to 30.3 MeV showed that an energy dependence of only VR and Ws (volume real and surface imaginary depths) is sufficient to reproduce the measurements. Coupled-channels (CC) analyses were made with a quadrupole-deformed optical-model potential and strong coupling of 3 2−, 5 2− and 7 2− levels of a K = 3 2 ground-state rotational band of 9Be. The 9Be(p, p0)9Be and 9Be(p, p2)9Be data from 13.0 to 30.3 MeV were analyzed simultaneously at each energy, varying only VR and Ws with energy, for a potential deformation of β = 1.1. Both SOM and CC analyses indicated the same energy dependence in VR, while Ws averaged 3.5 MeV lower in CC than in SOM, with both energy dependences consistent with previous analyses of nucleon scattering from 1p shell nuclei.

A broad anomaly was observed in the 9Be(p, p0)9Be excitation functions. Differential cross-section angular distributions were measured for 9Be(p, p0)9Be and 9Be(p, p2)9Be at lab energies of 13.0, 14.0, 15.0, 21.35 and 30.3 MeV and for 9Be(p, d0)8Be at 13.0, 14.0, 15.0 and 21.35 MeV. Angular distributions of polarization analysing powers for 9Be(p,p0)9Be, 9Be(p, p2)9Be and 9Be(p, d0)8Be were measured at 8.0, 11.0, 12.0, 13.0 and 15.0 MeV. A spherical optical-model (SOM) analysis of the elastic scattering angular distribution data from 13.0 to 30.3 MeV showed that an energy dependence of only VR and Ws (volume real and surface imaginary depths) is sufficient to reproduce the measurements. Coupled-channels (CC) analyses were made with a quadrupole-deformed optical-model potential and strong coupling of 3 2−, 5 2− and 7 2− levels of a K = 3 2 ground-state rotational band of 9Be. The 9Be(p, p0)9Be and 9Be(p, p2)9Be data from 13.0 to 30.3 MeV were analyzed simultaneously at each energy, varying only VR and Ws with energy, for a potential deformation of β = 1.1. Both SOM and CC analyses indicated the same energy dependence in VR, while Ws averaged 3.5 MeV lower in CC than in SOM, with both energy dependences consistent with previous analyses of nucleon scattering from 1p shell nuclei.</abstract><subject><genre>Keywords</genre><topic>Nuclear reactions</topic></subject><relatedItem type="host"><titleInfo><title>Nuclear Physics, Section A</title></titleInfo><titleInfo type="abbreviated"><title>NUPHA</title></titleInfo><genre type="Journal">journal</genre><originInfo><dateIssued encoding="w3cdtf">19730416</dateIssued></originInfo><identifier type="ISSN">0375-9474</identifier><identifier type="PII">S0375-9474(00)X0915-3</identifier><part><date>19730416</date><detail type="volume"><number>204</number><caption>vol.</caption></detail><detail type="issue"><number>3</number><caption>no.</caption></detail><extent unit="issue pages"><start>433</start><end>648</end></extent><extent unit="pages"><start>529</start><end>551</end></extent></part></relatedItem><identifier type="istex">0B396426C61FB6B2CFE96F59E347D92DA7D57722</identifier><identifier type="DOI">10.1016/0375-9474(73)90393-X</identifier><identifier type="PII">0375-9474(73)90393-X</identifier><recordInfo><recordContentSource>ELSEVIER</recordContentSource></recordInfo></mods></metadata><enrichments><istex:catWosTEI uri="https://api.istex.fr/document/0B396426C61FB6B2CFE96F59E347D92DA7D57722/enrichments/catWos"><teiHeader><profileDesc><textClass><classCode scheme="WOS">PHYSICS, NUCLEAR</classCode></textClass></profileDesc></teiHeader></istex:catWosTEI></enrichments></istex></record>Pour manipuler ce document sous Unix (Dilib)
