Spectroscopy of ${}^{26}$F

Abstract

The structure of the weakly-bound ${}_9^{26}$F${}_{17}$ odd-odd nucleus, produced from ${}^{27,28}$Na nuclei, has been investigated at GANIL by means of the in-beam ${\hat{I}}^3$-ray spectroscopy technique. A single ${\hat{I}}^3$-line is observed at 657(7) keV in ${}_9^{26}$F which has been ascribed to the decay of the excited J=$2^{+}$ state to the J=1${}^{+}$ ground state. The possible presence of intruder negative parity states in ${}^{26}$F is also discussed.
