Summary
Recent experimental results near 10 MeV obtained at Berkeley and Los Alamos are treated in terms of an energy-independent phase-shift analysis, complemented by an effective-range expansion analysis of the1 S 0 phase shifts. The one-pion-exchange dependence is confirmed but an anomaly is found near 10 MeV. The necessity and accuracy of further experimental work is indicated and discussed.
Riassunto
Si trattano i recenti risultati sperimentali attorno a 10 MeV ottenuti a Berkeley e Los Alamos in termini di un'analisi degli spostamenti di fase indipendenti dall'energia, completati da un'analisi dello sviluppo del raggio effettivo degli spostamenti di fase1 S 0. Si conferma la dipendenza dallo scambio di un pione ma si trova un'anomalia attorno a 10 MeV. Si indica e si discute la necessità e l'accuratezza di un ulteriore ricerca sperimentale.
Реэюме
Недавние экспериментальные реэультаты в области 10 МэВ, полученные в Беркли и Лос Аламосе, рассматриваются в терминах анализа фазовых сдвигов, независящих от энергии, дополненного анализом разложения эффективной области для фазовых сдвигов1 S 0. Подтверждается зависимость, связанная с однопионным обменом, но обнаружена аномалия вблизи 10 МэВ. Указывается и обсуждается необходимость и точность дальнейших экспериментальных исследований.
