We present a quantum-mechanical calculation of Stark linewidths from electron-ion collisions for the 2s{sub 1/2}-2p{sub 1/2,3/2}, {lambda}=2066 and 2067 {Angstrom}, resonance transitions in BIII. The results confirm previous quantum-mechanical R-matrix calculations, but contradict recent measurements and semiclassical and some semiempirical calculations. The differences between the calculations can be attributed to the dominance of small L partial waves in the electron-atom scattering, while the large Stark widths inferred from the measurements would be substantially reduced if allowance is made for hydrodynamic turbulence from high-Reynolds-number flows and the associated Doppler broadening. {copyright} {ital 1997} {ital The American Physical Society}
