The heat capacity of La2 \_xSl'xCuO 4 for the Sr-concentrations 0 ~< x ~< 0.3 was measured in the wide temperature range between 60 K and 80 mIC A homogeneous bulk superconducting transition was characterized by a steep jump of the heat capacity at To, AC/Tc = 13 mJ/K2/mol for x= 0.15.

We present measuxements of the low temperature specific heat (0.09K< T < 1.5K) of seven samples of the La2\_~Sr~CuO4 system (0.05< z <0.27). All the data were found to fit the expression, C = A(x)T -2 +a(x)T'~(~)+ fl(z)T 3. The coefficient of the nuclear specific heat contribution A(z) was found to
