Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

Laser spectroscopic measurements of the isotope shift in an atomic
transition are well known to provide accurate data on nuclear charge
radii. For short-lived isotopes it is particularly useful, since it is
the only method that provides nuclear-model independent charge radii.
However, for the very light elements the contributions of the nuclear
volume effect to the total isotope shifts is on the order of 1E-4 to
1E-5. By combining accurate theoretical calculations of the
mass-dependent part of the isotope shift and precision measurements we
succeeded in measuring the nuclear charge radii of all lithium isotopes,
including the exotic halo nucleus 11Li. I will report on these
measurements and conclusions about the nuclear structure of 11Li.
