We firstly calculated the E1 decay width of $\\chi_{c1}$(1P), the result is in agreement with experimental data excellently, then we calculated the case of $\\rm X(3872)$ with the assignment that it is $\\chi_{c1}$(2P). Results are: ${\\Gamma}({\\rm X(3872)}\\rightarrow \\gamma \\sl J/\\psi)=33.0$ keV, ${\\Gamma}({\\rm X(3872)}\\rightarrow \\gamma \\psi(2S))=146$ keV and ${\\Gamma}({\\rm X("},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1006.3363","kind":"arxiv","version":4},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
