Аннотация
The effect of bound He3 impurity pairs located in surface states of He3−He4 liquid solutions on system properties is studied. It is shown that in the temperature range below the binding energy, consideration of the interaction leading to pair formation significantly changes the temperature dependence of the excess surface tension produced by the He3 impurities. The results obtained are compared with data of earlier studies.
