First observation of γ rays emitted from excited states south-east of 132Sn: The π g−1 9/2 ⊗ ν f7/2 multiplet of 132In83

Artículo escrito por muchos autores, sólo se referencian el que aparece en primer lugar, el nombre del grupo de colaboración y los autores que firman como pertenecientes a la UAMFor the first time, the γ decay of excited states has been observed in a nucleus situated in the quadrant south-east of doubly magic 132Sn, a region in which experimental information so far is limited to ground-state properties. Six γ rays with energies of 50, 86, 103, 227, 357, and 602 keV were observed following the β-delayed neutron emission from 133Cd85, populated in the projectile fission of a 238U beam at the Radioactive Isotope Beam Factory at RIKEN within the EURICA project. The new experimental information is compared to the results of a modern realistic shell-model calculation, the first one in this region very far from stability, focusing in particular on the π0g−1 9/2 ⊗ ν1f7/2 particle-hole multiplet in 132In83. In addition, theoretical estimates based on a scaling of the two-body matrix elements for the πh−1 11/2 ⊗ νg9/2 analog multiplet in 208Tl127, one major proton and one major neutron shell above, are presentedThis work was supported by the Spanish Ministerio de Ciencia e Innovación under Contract No. FPA2011-29854-C04 and the Spanish Ministerio de Economía y Competitividad under Contract No. FPA2014-57196-C5- 4-P, the Generalitat Valenciana (Spain) under Grant No. PROMETEO/2010/101, the National Research Foundation of Korea (NRF) grant funded by the Korea government (MEST) (No. NRF-2012R1A1A1041763), the Priority Centers Research Program in Korea (2009-0093817), OTKA Contract No. K-100835, JSPS KAKENHI (Grant No. 25247045), the European Commission through the Marie Curie Actions call FP7-PEOPLE-2011-IEF under Contract No. 300096 and the German BMBF (No. 05P12RDCIA and No. 05P12RDNUP), and Helmholtz International Center for FAI
