EFFECT OF IRRADIATION BY BORON IONS ON THE CHARACTER 
OF REALIZATION OF TWINNING AND SLIP UNDER PROLONGED (MORE THAN 60 
SEC) LOADING OF SINGLE CRYSTALS OF BISMUTH

The twinning of single crystals of bismuth irradiated 
by boron ions with an energy of 25 keV and a dose of 1017 ion/cm2, 
in the case of prolonged (more than 60 sec) loading of a crystal 
is studied. It is found that prolonged exposure of a crystal to 
a concentrated load promotes a decrease in the number of twins in 
the concentrator of external stresses. An increase of temperature 
up to 400 K stimulates the process of slip in the realization 
of plastic deformation of a crystal.
