| الوصف: | The beta-decay half-lives of 94 neutron-rich nuclei Cs144-151, Ba146-154, La148-156, Ce150-158, Pr153-160, Nd156-162, Pm159-163, Sm160-166, Eu161-168, Gd165-170, Tb166-172, Dy169-173, Ho172-175, and two isomeric states Er-174m, Dy-172m were measured at the Radioactive Isotope Beam Factory, providing a new experimental basis to test theoretical models. Strikingly large drops of beta-decay half-lives are observed at neutron-number N = 97 for Ce-58, Pr-59, Nd-60, and Sm-62, and N = 105 for Eu-63, Gd-64, Tb-65, and Dy-66. Features in the data mirror the interplay between pairing effects and microscopic structure. r-process network calculations performed for a range of mass models and astrophysical conditions show that the 57 half-lives measured for the first time play an important role in shaping the abundance pattern of rare-earth elements in the solar system. ; Rare Isotope Science Project - Ministry of Education, Science, and Technology (MEST); National Research Foundation (NRF) of Korea [2013M7A1A1075764]; KAKENHI [25247045]; RIKEN Foreign Research Program; Spanish Ministerio de Ciencia e Innovacin [FPA 2009-13377-C02, FPA2011-29854-C04]; UK Science and Technology Facilities Council; U.S. Department of Energy, Office of Science, Office of Nuclear Physics [DE-AC02-06CH11357]; NNSA of the U.S. DOE at Los Alamos National Laboratory [DE AC52-06NA25396]; NASA [NNX10AH78G]; National Research Foundation Grant - Korean Government [NRF-2009-0093817, NRF-2015R1D1A1A01056918, NRF-2016 R1A5A1013277, NRF-2013R1A1A2063017]; Hungarian Scientific Research Fund OTKA [K100835] ; SCI(E) ; ARTICLE ; 7 ; 118 |
