The temperature dependence between 0.05 and 1.5 K of the width of a photochemical hole has been studied in the spectrum of H,-octaethylporphin impurity in an amorphous polystyrene matrix. At T= 0.5 K. the holewidths were 26 MHz for X, = 620.1 nm and 34 MHz for X, = 621.8 nm, exceeding the lifetime-l

A cryostat is described which is designed for the research of inelastic scattering of neutrons on a large volume (3.5 I) of He 4 between 4.2 and 0.5 K. Temperatures lower than 1.3 K are produced by means of pumping out vapour above liquid He 3 (~ 330 cm 3) with an adsorption pump (1 kg of coal CKT-2
## Abstract The thermodynamic properties of the six‐membered cyclic urethane, viz. 5,5‐dimethylperhydro‐1,3‐oxazin‐2‐one (DIO, 1) and the corresponding polymer, poly(5,5‐dimethyl‐2‐oxo‐1‐oxa‐3‐azahexamethylene) (PDIO, 2) were studied by calorimetry. The temperature dependence of the heat capacity a
