I R I S facility
Nuclear spectroscopy group.
Main proposals of our group for on-line experiments
at IRIS mass separator.
- Identification of new short
lived isotopes far off the stability line.
Half-lifes and main decay properties have been studied.
- Identification of the proton
drip line in the region of rare earth elements.
Alpha decay energies for long decay chains were studied carefully usimg
Si(Au)-solid state detectors to deduce masses of nuclei far off the beta
stability line.
- Q-beta
decay energies and deduced masses of short lived isotopes.
This research was done for neutron deficient isotopes of rare earth
elements. End point energies for beta spectra were measured with high accuracy
using Ge(HP) solid state detectors.
- Search for the delayed fission of very neutron rich Francium
isotopes.
The very low limit was set for this decay mode of isotopes under
investigation. The r-process path problem was considered in accordance to
obtained results.
The time-of-flight method was applied to recoiled nuclei to study the
delayed neutron decay.
