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 0o. 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.
