N2 - The Gamow-Teller (GT) states in [Formula presented] have been studied via the [Formula presented] and [Formula presented] coincidence experiments. The GT states in [Formula presented] at [Formula Presented], where both [Formula Presented] and [Formula Presented] states exist, are excited strongly in the [Formula presented] reaction at [Formula presented] and [Formula Presented]. Proton emissions from the GT states in [Formula presented] to the hole states in [Formula presented] have been observed with solid-state detectors in coincidence with high energy tritons measured with a magnetic spectrometer. For the first time, the [Formula Presented]-ray emissions from the excited states in [Formula presented] and in [Formula presented], following the [Formula presented] reaction at intermediate energies, have also been observed in coincidence with tritons. Strengths of proton decay into several neutron-hole states in [Formula presented] and [Formula Presented]-decay strengths are used to discuss the wave functions of the GT states in [Formula presented]. The [Formula Presented] and [Formula Presented] GT states do only weakly decay into a [Formula Presented] neutron-hole state at [Formula Presented] in [Formula presented], which is strongly excited via the [Formula presented] reaction. The wave functions of the [Formula Presented] and [Formula Presented] GT states with the [Formula Presented] neutron-hole configuration are inferred to be strongly coupled to [Formula Presented] configurations, making fragmented GT strengths in [Formula presented].
