The masses of 246Es and 249,250,252Md were measured for the first time. Using the masses of 249,250Md as anchor points for \u03b1 decay chains, the masses of heavier nuclei, up to 261Bh and 266Mt, were determined. These new masses were compared with theoretical global mass models and demonstrated to be in good agreement with macroscopic-microscopic models in this region. The empirical shell gap parameter \u03b42n derived from three isotopic masses was updated with the new masses and corroborates the existence of the deformed N=152 neutron shell closure for Md and Lr.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "American Physical Society  "}]}, "item_5_relation_10": {"attribute_name": "PubMed\u756a\u53f7", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "29756864", "subitem_relation_type_select": "PMID"}}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1103/PhysRevLett.120.152501", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2018 American Physical Society "}, {"subitem_rights": "Published by the American Physical Society under the terms of the Creative Commons Attribution 4.0 International license.
