摘要
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 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.
An experimental study of high-spin states in ^(79)Kr has been performed at the GASP array using the reaction ^(55)Mn(^(30)Si, αpn). Nine new states along with 10 new gamma ray transitions were found in the K~π=5/2^- band in ^(79)Kr. Three band crossings, associated with the alignments of a πg_(9/2) pair and a πg_(9/2) 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.
