TEXT: The term. "theoretical strength' is considered which is understood
as the maximum quasi-elastic.f6rce in the iviiform deformation of an ideal solid
from defects in the.absence of heat fluctuations. The destruction process
in the case considered represents a dissociation &tid difters from the real de-
struction process with the formation.of new free surfaces of rupburt). The bi-
.,~.,nomial fornula for the potential energy of a particle, U(r) - -A,/rm + B/rn is
examined which Is correot for any type of chemioal bond. The quasi-elastic

TRANSLATION:. glass is irradiated with galwa royis, an inereMe U observed in
the modulus of longitudinal elasticity'R and in the slae&r modulus')A-. This can be
-.attributed to the healing of the deracts of the glasii structure V the diffusion of' I
the modifier atoms. Annealing has a similar influenea on the change in the elastic
parameters. The tangent.of the angle of the dielectj:%Lc losses and the dielectric
constant also increase during the irradiation ~rocesjs-~ This.is probably connected,
