Nine new states along with 10 new gamma ray transitions were found in the Kπ=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 5h11/2 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. 关 键 词：氪79 高自旋态 原子核 质子队列 中子队列 自旋轨道 形态
