{"doi":"10.1063/5.0101903","title":"Electron affinity of tantalum and excited states of its anion","abstract":"<jats:p>The tantalum anion has the most complicated photoelectron spectrum among all atomic anions of transition elements, which was the main obstacle to accurately measure its electron affinity via the generic method. The latest experimental value of the electron affinity of Ta was 0.323(12) eV, reported by Feigerle et al. [J. Chem. Phys. 74, 1580 (1981)]. In the present work, we report the high-resolution photoelectron spectroscopy of Ta− via the slow-electron velocity-map imaging method combined with a cryogenic ion trap. The electron affinity of Ta was measured to be 2652.38(17) cm−1 or 0.328 859(23) eV. Three excited states 5D1, 3P0, and 5D2 of Ta− were observed, and their energy levels were determined to be 1169.64(17) cm−1 for 5D1, 1735.9(10) cm−1 for 3P0, and 2320.1(20) cm−1 for 5D2 above the ground state 5D0, respectively.</jats:p>","journal":"The Journal of Chemical Physics","year":2022,"id":43190,"datarank":0.24141568686511508,"base_score":1.6094379124341003,"endowment":1.6094379124341003,"self_citation_contribution":0.24141568686511508,"citation_network_contribution":0.0,"self_endowment_contribution":0.24141568686511508,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":4,"citer_count":1,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":205647,"name":"Xiaoxi Fu","orcid":null,"position":1,"is_corresponding":false},{"id":205648,"name":"Xiaolin Chen","orcid":null,"position":2,"is_corresponding":false},{"id":205649,"name":"Yuzhu Lu","orcid":null,"position":3,"is_corresponding":false},{"id":205650,"name":"Chuangang Ning","orcid":"0000-0002-3158-1253","position":4,"is_corresponding":false},{"id":109678,"name":"Sheng Li","orcid":"0000-0002-2436-0962","position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":1.6094379124341003,"endowment":1.6094379124341003,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"35922342","pmcid":null,"openalex_id":"https://openalex.org/W4283827726","authors":[],"funders":[{"funder_name":"National Natural Science Foundation of China","grant_id":"11974199","title":null},{"funder_name":"National Natural Science Foundation of China","grant_id":"91736102","title":null},{"funder_name":"National Key Research and Development Program of China","grant_id":"2018YFA0306504","title":null}],"total_grants":3,"fwci":0.6115,"citation_percentile":0.65883074,"influential_citations":0,"citation_trend":[{"year":2023,"count":2},{"year":2024,"count":1},{"year":2025,"count":1}],"oa_status":"bronze","license":null,"oa_locations":[{"url":"https://pubs.aip.org/aip/jcp/article-pdf/doi/10.1063/5.0101903/16546653/044302_1_online.pdf","host_type":"journal"},{"url":"https://pubs.aip.org/aip/jcp/article-pdf/doi/10.1063/5.0101903/16546653/044302_1_online.pdf","host_type":"BRONZE"},{"url":"https://pubs.aip.org/aip/jcp/article-pdf/doi/10.1063/5.0101903/16546653/044302_1_online.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1063/5.0101903","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/35922342","host_type":"repository"}],"fields_of_study":["Advanced Chemical Physics Studies","Atomic and Molecular Physics","Electron and X-Ray Spectroscopy Techniques","Medicine","Chemistry","Physics"],"mesh_terms":[],"keywords":["Electron affinity (data page)","Tantalum","Excited state","Ion","X-ray photoelectron spectroscopy","Atomic physics","Chemistry","Electron","Ionization energy","Ground state","Binding energy","Analytical Chemistry (journal)","Ionization","Molecule","Nuclear magnetic resonance","Physics"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Affordable and clean energy"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-14T19:56:29.914896Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
