The [Formula Presented] rotational band has been extended beyond the first alignment crossing, which was found at rotational frequency [Formula Presented]. Two different scenarios for describing this crossing are considered: the alignment of an [Formula Presented] proton or [Formula Presented] neutron pair and it is concluded that a proton band crossing is more likely. A systematic study of the rotational alignment crossings in the [Formula Presented] bands in the [Formula Presented] isotopes of [Formula presented] and [Formula presented] is presented. © 2003 The American Physical Society.eninfo:eu-repo/semantics/closedAccessArticle68510.1103/PhysRevC.68.0543072-s2.0-0742288739N/AWOS:000187578300017Q2
