Study of some16O states at high excitation energy

Исследование некоторых состояний16O при высоких энергиях возбуждения

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The particle-particle angular-correlation method is applied to the reaction12C(6Li, d)16O→α+12C. Deuterons were detected at Φ1=0°. Spin and parity of some highly excited16O states are deduced. Analysis of the correlation patterns indicates that a direct transfer is a dominant mechanism. The angular correlation corresponding to the16O21.8→α+12C4.43 is specially analysed and interference effects due to the differentl values involved in the decay are discussed.

Riassunto

Il metodo delle correlazioni angolari particella-particella è applicato alla reazione12C(6Li, d)16O→α+12C. Si determinano spin e parità di alcuni stati del16O ad alta energia di eccitazione, effettuando la misura della correlazione angolare deuterone-alfa nel caso speciale in cui il deuterone è rivelato a zero gradi (Φ1=0°). L'analisi della curva di correlazione indica che il meccanismo dominante è quello di un trasferimento diretto. Si è analizzata in maniera particolare la correlazione angolare corrispondente al decadimento16O21.8→α+12C4.43 e si sono discussi gli effetti di interferenza dovuti ai differenti valori dil permessi nel decadimento.

Резюме

Метод угловых корреляций между частицами применяется к реакции12C(6Li, d)16O→α+12C. Детектируются дейтроны при Φ1=0°. Определяются спин и четность некоторых высоковозбужденных16O состояний. Анализ корреляций указывает, что в этой реакции доминируюций механизм представляет прямую передачу. Анализируется угловая корреляция, соответствующая реакции16O21.8→α+12C4.43. Обсуждаются интерференционные эффекты, обусловленные различными величинамиl, включенными в этот распад.
