Abstract
Energy transport by a strong resonance line
like Lyman 
has been studied numerically.
The corona region of laser-produced Li plasmas is assumed to be
the isothermal expansion model.
As a result, though the peak intensity of Lyman keeps Planckian value, width of the line becomes broader
during the transmission in the corona region.
If the optical depth could be controlled thicker much more than unity,
available power exceeds the value of surface area
intensity of Planckian
line width of emissivity, and
the EUV light source for the semiconductor lithography can be designed
by Li target.
