and composed of tw o continuous zones:the first one originated from the host absorption about 170nm

the second one originated from the absorption of the transition 3d

→3d

of Mn

around 190～200nm.The absorption more than 200nm was very weak.It is said th at the absorption of VUV was very strong

and the absorption of UV was weak in the system of Ba
