Half-lifes and main decay properties have been studied.
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.
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.
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.
