Turning it into a method that predicts full distributions of fragment masses and energies without tuning to fission data is still unsolved.","posed_since":"","precise":"Extend time-dependent density-functional theory with pairing (TDHFB, TDSLDA) by a beyond-mean-field treatment of fluctuations (time-dependent generator coordinate method, stochastic mean field, or time-dependent random phase approximation) so that it predicts the mass and charge yields $Y(A)$, $Y(Z)$, the total kinetic energy distribution $\\mathrm{TKE}(A)$ and their widths for $\\mathrm{235U}(n_{\\mathrm{th}},f)$ and $\\mathrm{252Cf}(\\mathrm{sf})$ within experimental uncertainty. The functional must be fixed by non-fission data only, and the answer is a demonstration of such predictions.","problem_ref":null,"references":"","settled_by":"Published yields and kinetic-energy distributions from a fluctuation-including microscopic method, with no fission-data fit, agreeing with evaluated data for several actinides and predicting a measured but unseen case.","status_note":"","title":"Predictive time-dependent density-functional dynamics of fission yields","topic_ref":"4682ec98f6efef769b56a4880afd87dd00cb0bc4ad4f0a7af1b11de1483f7592"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"1a01c6bb143975b4bef184b84c6237d547c9545c445faeb5757062e005874fcd","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"8058abb87ecf35ce7013b653683613ec3ebf29c63373213632e5b8e066d7bb0c","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"qgdHRjKnPDdnV9ldzy2MGhEK6O-MyUGqGARaEyj5bZnFbOQEOnIV7sDNL2C8Tew7u8z3lWYFGXjpqFF8W2aFDQ"},"schema":"pubphys.envelope/1"},"record_hash":"1a01c6bb143975b4bef184b84c6237d547c9545c445faeb5757062e005874fcd","leaf_index":1754}
