Abstract

Excitation spectra of 11C are measured in the 12Cðp; dÞ reaction near the η0 emission threshold. A proton beam extracted from the synchrotron SIS-18 at GSI with an incident energy of 2.5 GeV impinges on a carbon target. The momenta of deuterons emitted at 0° are precisely measured with the fragment separator
(FRS) operated as a spectrometer. In contrast to theoretical predictions on the possible existence of deeply bound η0-mesic states in carbon nuclei, no distinct structures are observed associated with the formation of bound states. The spectra are analyzed to set stringent constraints on the formation cross section and on the hitherto barely known η0-nucleus interaction.
