Abstract :
The relaxation times T1 for the grouud state levels in ruby were measured in the temperature range 4.2 to 1.6°K for the various concentrations of the 
ions 
from 0.05 to 0.7 percent. The dependence 
of the form 
with 
has been obtained for the different transitions. The measurements of relaxation times for 
transition at zero magnetic field were especially aimed at establishing a form of dependence because of the absence of the cross relaxation effects in this case. The normal temperature dependence 
has been obtained at all concentrations in comparison with anomalous dependences observed at high concentrations by some researchers.
