Summary

The elastic scattering of alpha-particles from6Li has been studied in the incident alpha energy range between 3.30 and 5.00 MeV. A shape analysis of the resonance structures near 3.502 and 4.250 MeV alpha energies leads to the assignmentsJπ=2 or 4 andJπ=2+ respectively for the levels in10B at 6.56 and 7.01 MeV. The total widths of these two levels are found to be (26±3) keV and (110±15) keV respectively in the centre-of-mass system.

Состояния в10В иэ упругого рассеяния альфа-частиц на6Li

Реэюме

Было исследовано упругое рассеяние альфа-частиц на6Li для знергий падаюших альфа-частиц в области между 3.30 и 5.000 МзВ. Аналиэ форм реэонансных структур вблиэи знергий альфа-частиц 3.502 и 4.250 МзВ приводит к приписываниюJπ=2 или 4иJπ=2+ соответственно для уровней в10В при 6.56 и 7.01 МзВ. Получается, что полные щирины зтих двух уровней составляют соответственно (26±3)кзВ и (110±15)кзВ в системе центра масс.

Riassunto

Si è studiato lo scattering elastico di particelle α su6Li per energie delle particelle α incidenti fra 3.30 e 5.00 MeV. Un’analisi dell’andamento delle strutture di risonanza per energie delle particelle α fra 3.502 e 4.250 MeV permette di assegnareJπ=2 o 4 eJπ=2+ rispettivamente per i livelli nel10B a 6.56 e 7.01 MeV. Si trova per le ampiezze totali di questi due livelli il valore (26±3) keV e (110±15) keV nel sistema del centro di massa.
