[Formula Presented] decay of [Formula Presented]

Summary, in English

Information on gross [Formula Presented]-decay properties of neutron-rich noble gas isotopes [Formula Presented] was obtained at the PSB-ISOLDE facility at CERN using isobaric selectivity achieved by the combination of a plasma ion source with a cooled transfer line and subsequent mass separation. A doubly charged beam was used in the case of [Formula Presented] to suppress the corresponding multicharged background from heavier noble gas fission products. The comparison of the obtained data with results of quasiparticle random-phase approximation calculations indicates that the [Formula Presented] shell is not disturbed significantly for neutron-rich Ar nuclei. The obtained results are useful for better understanding of the origin of the [Formula Presented] isotopic anomaly discovered in inclusions from the Allende meteorite.
