Quasielastic scattering in the interaction of ultracold neutrons with a liquid wall and application in a reanalysis of the Mambo I neutron-lifetime experiment

RADIOACTIVITY ¹NN(β^-); analyzed T_1/2 using theory of ultracold and very cold neutron scattering on viscoelastic surface waves up to second-order perturbation theory. Reanalyzed 1989 neutron-lifetime experiment using ultracold neutron storage in a Fomblin-coated vessel by Mampe et al [Phys. Rev. Lett. 63, 593 (1989)]; revised the neutron lifetime value from 887.6(30) s to 882.5(21) s. Comparison with other neutron lifetime measurements. Relevance to Standard Model (SM) predictions and the up-down quark mixing coefficient V²_ud.
