Determination of the Lifetime of the 1+ State in 30Na — •Sebastian Heil and Marina Petri for the E05122 collaboration — TU Darmstadt, Darmstadt, Deutschland
30Na is located at the "Island of Inversion" at N=20. The experiment E05122 was performed at the National Superconducting Cyclotron Laboratory and investigated the low-lying structure of the odd-odd nucleus 30Na via nucleon removal reactions from 31Mg, 30Mg and 31Na [1].
The aim of the work to be presented is the determination of the lifetime of the first excited 1+ state in 30Na. This is achieved via peak shape analysis of the obtained γ-ray spectrum. The analysis will be discussed and the results will be compared to large scale shell model calculations.
This work was supported by DOE contract No. DE-AC02-05CH11231, by the National Science Foundation under Grant PHY-1102511 and by the Helmholtz International Center for FAIR within the framework of the LOEWE program (Landesoffensive zur Entwicklung Wissenschaftlich-Ökonomischer Exzellenz) launched by the State of Hesse.
