Measured stark widths of BI, BII, BIII and Nal spectral lines

Stark widths of six spectral lines from neutral and multiple ionized boron and three spectral lines from neutral sodium spectra have been measured in a pulsed linear arc plasma. All the measurements have been done in the electron density range of 1.66 x 10(23)-2.55 x 10(23) m-3 and in the electron temperature range of 40 000-50 000 K. Some of these experimental values are compared with existing theoretical data.
