An experimental study of high-spin states in ⁷⁹Kr has been performed at the GASP array using the reaction ⁵⁵Mn(³⁰Si, αpn). Nine new states along with 10 new gamma ray transitions were found in the K^π=5/2^- band in ⁷⁹Kr. Three band crossings, associated with the alignments of a πg9/2 pair and a πg9/2 pair and also a high-j 5h_11/2 intrude orbital, were observed at rotational frequency h=0.50, 0.65 and 0.90 MeV, respectively. A cranked shell model analysis has been made to interpret the experimental results.
