Summary
The annihilation\(\bar pn\) → π−π0 has been studied in a D2 bubble chamber at several beam momenta between 1.0 and 1.6 GeV/c. The cross-section has been measured to be (110±15) μb at an average beam momentum of 1.3 GeV/c. The study of the angular distribution shows the presence of anL = 3 wave.
Riassunto
Si è studiata l’annichilazione\(\bar pn\) → π−π0 in camera a bolle a deuterio per parecchi impulsi del fascio tra 1.0 ed 1.6 GeV/c. Si è trovato che la sezione d’urto misurata è (110 ± 15) μb ad un impulso medio del fascio di 1.3 GeV/c. Lo studio della distribuzione angolare indica la presenza di un’ondaL = 3.
Реэюме
Исследуется аннигиляция\(\bar pn\) → π−π0 в D2 пуэырьковой камере в области импульсов от 1.0 до 1.6 ГзВ/с. Иэмеренное поперечное сечение составляет (110±15) µб при среднем импульсе пучка 1.3 ГзВ/с. Исследование углового распределения укаэывает на наличиеL=3 волны.
