DESCRIPTION:Speakers: Kabita Kundalia (Bose Institute\, India)\nIn stellar
  evolution\, the rate of 12C(α\,γ)16O reaction controls the C/O abundanc
 e ratio at the end of the helium burning phase\, thus defining the further
  course of development. At stellar temperatures of around 300 keV\, the cr
 oss section of 12C(α\,γ)16O is ∼ 10−17 b\, which cannot be measured 
 using current technology. The α−capture reaction populating the natural
 -parity states of the residual nuclei\, is an effective indirect tool for 
 studying these types of reactions. In this case\, it corresponds to the al
 pha pickup by 12C to populate states of 16O\, predominantly the 6.917 MeV 
 state. Loosely bound stable nuclei with prominent α−cluster structure\,
  such as 6\,7Li\, 11B have also been used in such studies provided that th
 ese are "direct" α−transfer and do not proceed via a compound nucleus. 
 However\, the breakup contributions from such nuclei have a significant im
 pact on the transfer channels. Interestingly\, the 7Be nucleus\, though ha
 ving an α−cluster structure and a lower breakup threshold of 1.58 MeV\,
  demonstrates lower breakup contribution compared to transfer cross sectio
 n. In this context\, we carried out an experiment at HIE-ISOLDE\, CERN\, w
 ith 7Be + 12C at E = 5 MeV/A to study α−transfer reactions populating s
 tates in 16O\, that dominantly contribute to the He-burning process. Preli
 minary results would be presented.\n\nhttps://indico.ific.uv.es/event/6372
