The precise measurements of the spectral line profiles
near the short-wavelength limit of the Lyman series of
Al are reported. The spatially resolved narrow-band spectra
were attributed to macroscopic plasma parameters by using
the results of 1D and 2D hydrodynamic plasma modeling.
The gradual merging and broadening of the spectral lines
Al Lyε–θ was compared to the
synthetic spectra produced by atomic physics codes. The
discrepancies between the experimental and theoretical data
indicate the limits for applicability of standard theoretical
models.
