Structural stability of the plasma sprayed alumina has been studied after its exposure to 4 K fast-neutron and gamma irradiation. The fast-neutron fluence (E ΟΎ 0.1 MeV) was 1.8 Γ 10 22 n m -2 . As shown by X-ray diffraction and high-resolution transmission electron microscopy (HRTEM), the microstruc

β¦ Synopsis
Neutron, plioton or cl~argctl particle activation of aqueous san~plcs or biologicnl tissues at low temporaturc offers various advantages in analysis. Thus, elenicntal * The solidification may also bc carried out advantageously by freezing the samples in liquid nitrogen. However. this technique needs special care in order to avoid cracking of the containers.

This paper reviews some of the literature relating to radiation damage in composite materials and relates the results to the chemical structure of the matrix resin. A mechanism of radiation damage at low temperatures is outlined, and those structural features that contribute to radiation stability a
The specific heat of glassy carbon was investigated in the temperature range of 0\*44-4\*5"K. The specific heat follows a relation C = aT3+ yT, with y going through a ma~mum and a! increasing with increase in heattreatment temperature. On the average the cubic specific heat term is about the same as
