Description

The anticrossing spectra of the n = 6, 7, 8 1D-3D states of 3He has been observed. From these measurements precise values of the electrostatic singlet-triplet separation of these states have been obtained and are found to differ systematically from the accepted values of the 4He singlet-triplet separation by approximately 34 MHz. We have investigated mass dependent contributions to both the energy level structure and the magnetic-tuning characteristics of the states of interest. We have found no mechanism that can explain such a large difference in the electrostatic-energy separation of the singlet and triplet D states between the two helium isotopes
