Gorter C.J. (Ed.) (Ed.) Progress in Low Temperature Physics, Volume VI

Amsterdam: North-Holland, 1970, -451 p.Though the fields of research in low temperature physics do not vary quickly, the problems awaking active interest, being tackled in different research centres and by different approaches, often shift quite rapidly. Thus, so far there has been no lack of subjects to be studied and no lack of scientists working at the main scientific fronts, and it was not too difficult to persuade some of these scientists to compose a deliberate review of the fields in which they are creative experts. From time to time the fields, or the situation, change so radically that new fields of research have to be presented.
In the preface of Volume 5 of this series of Progress books it was stressed that the chapters in the later volumes often contained narrower fields with relatively more formulae, the choice of the subjects presented in one volume depending sometimes on rather secondary circumstances.
It is reasonable that a basic paper, such as that of Feynman in Volume I, has been followed by several specialised investigations and discussions. The first chapter of the present volume, written by Langer and Reppy, gives an example. Wheatley's paper on ³He has been preceded by quite a series of papers in the earlier volumes. But the present one is concentrated on temperatures far below 1 K and thus it also fulfills the wish to consider quite low temperatures and their techniques. The paper on pressure effects in superconductors by Boughton, Olsen and Palmy succeeds Squires' short contribution to Volume I, while Wielinga's calculations may be considered as a refined analysis of some of the problems introduced by Domb and Miedema in Volume IV. Durieux's paper on the International Practical Temperature Scale of 1968 is analogous to the earlier last chapters of the Volumes II and IV, in which very low temperature thermometry has been introduced...Intrinsic critical velocities in superfluid helium, J,S.
