Abstract
In a precision measurement of the spectrum of ultracold neutrons as it evolves during storage in a "neutron bottle" we have
observed an indication of a surprising heating by
10
-10 eV, occurring during the initial several 100 s of storage. We have not found any simple
explanation. The data are, however, consistent with unconventional ideas proposed previously by two of us.
