Résumé
Des mesures de la section efficace, du pouvoir d'analyse, et de la probabilité du renversement du spin sont en accord avec M1 pour le pic à 9,0 MeV dans la réaction 90 Zr(p,p')90Zr à 319 MeV, mais elles ne sont pas définitives. Des mesures de S nn montrent une section efficace d'excitation du spin qui est importante de 8 à 25 MeV.
Abstract
Measurements of the cross section, analyzing power, and spin-flip probability are consistent with an M1 assignment for the 9.0 MeV peak in the 90Zr(p,p')90Zr reaction at 319 MeV, but they are not definitive. The spin-Clip measurements reveal a large spin-excitation cross section from 8 to 25 MeV excitation.
