Description

Motivated by several theoretical cluster calculations that predict the existence of the 0₆⁺ state in ¹⁶O located at 15.1 MeV as a very good candidate for the equivalence of the Hoyle state in ¹²C, a high resolution measurement of ¹⁶O spectrum in coincidence with the ¹⁶O decay products was proposed using a (p,t) reaction at 200 MeV and 0^o. The decay products of the excited ¹⁶O recoil nucleus were detected by means of Double Sided Silicon Detectors and the outgoing tritons were identified in the K600 magnetic spectrometer focal plane. Data were collected with targets containing ¹⁸O, ¹⁶O, ¹²C and ⁷Li. First results on precise measurement of energy spectra of the corresponding recoil nuclei using the K600 as the master trigger and extracted cross sections will be discussed.
