Abstract
The absolute optical oscillator strengths for the individual He 11S to n1P (n=2-7) transitions have been measured using dipole (e, e) spectroscopy at high energy resolution. The results, which include the first measurements above n=3, are in excellent agreement with earlier published quantum mechanical calculations performed using very accurate correlated wavefunctions for helium.Keywords
