Abstract
Visible metal precipitation of a golden luster has been observed in Cs
MnCl3 . 2H(2)O which was irradiated with X- or gamma-rays at room temp
erature. It does not occur when it is irradiated at 77 K and then warm
ed to room temperature. A continuous optical absorption was observed r
anging from 2 eV to higher energy more than 5.50 eV (225 nm), An absor
ption band overlaps at 3.55 eV (350 nm), which is nearly the same as t
hose of the V-k center (Cl-2(-)) in KCl and RbCl. It suggests that the
3.55 eV band originates from the self-trapped hole centers (Cl-2(-))
in the present crystal.
