An answer is a first-principles calculation matching $P(v_{f})$ within experimental error for both initial states.","problem_ref":null,"references":"","settled_by":"First-principles nonadiabatic scattering calculations with an accurate NO/Au potential and anion state that reproduce the state-to-state molecular-beam data.","status_note":"","title":"Vibrational energy loss of NO molecules colliding with gold","topic_ref":"aa1669ae0dd7fb5df9048991b7b6472f6d13dde0228a4ba5521d38de86ed2a38"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"779870cd17cf5ea542432a914eb0ad787933f130d908bb0b4a93724348a52241","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"9fffe377fa2f518ec7527786b0dbc271e3c3ee9c700d65f0ec2061dbf00d65f6","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"UjiwO8Qlq2WbphDkCko6DZDJaaIZ4ivAn8TEzhn5fOgUY5ioDIvPwKotCeiVJwWAByRnO97s8iyP0wDl-QsaBg"},"schema":"pubphys.envelope/1"},"record_hash":"779870cd17cf5ea542432a914eb0ad787933f130d908bb0b4a93724348a52241","leaf_index":879}
