Abstract Theγ-decay of 9338Ar levels between 6.84 and 10 MeV excitation energy has been measured using the35Cl(α,pγ) reaction atE α=14 MeV. A previous measurement of the same reaction could be exploited in the light of the present results, yielding spin(-parity) assignmentsJ π(7,070)=5-, J(7,507)=7,5,J π(8,077)=7+, J(8,129)=5,6 and J(8,488)=7,5. Theγ-decay modes of yrast levels, which have been previously observed in heavy ion induced reactions, are revised leading to major changes in their spin-parity assignments. New candidates for theJ π=8- and 9+ levels were found in the levels at 9,644 and 9,928 keV excitation energy, respectively. A comparison of yrast levels with shell-model calculations is satisfying.
