Laser group of the IRIS
facility
The scientific activity of the laser group of IRIS is concerned with
the production and investigation of the nuclides far from beta-stability
line. The methods of atomic laser spectroscopy that are used for these
studies enables one to obtain the main groundstate nuclear characteristics
(mean-square charge radii, spins, electromagnetic moments) from the isotope
shifts and the atomic hyperfine structure measurements.
Experimental techniques used:
-
Method of the resonance photoionization spectroscopy in the laser ion source.
The main advantage of this method is the very high sensitivity (measurements
at the production rates down to 100 atoms of investigated isotope per second
are possible). Recently the new data on the short-lived isotopes 155Yb,
154Tm, 154mTm, 153Tm have been obtained by using of this method.
-
Method of the resonance photoionization spectroscopy in atomic beam [1].
-
Method of the collinear fluorescent spectroscopy (LARISA
project).
