“…Helium and argon are of special interest, for the data obtained by different established techniques are available. Kannuluik and his group (15)(16)(17), Srivastava and Saxena (37), and Srivastava and Barua (36) have used the thick-wire variant of the hot-wire cell, while Weber (47, 48), Johnston and Grilly (14), and von Ubisch (43) have exploited the thin-wire variant of the hot-wire method. On the other hand, Waelbroeck and Zuckerbrodt (45), Cheung, Bromley, and Wilke (3), Lenoir and Comings (22), and Keyes (18) have employed concentric cylinders; while Walker, de Haas, and Westenberg (46) have used a flow method.…”
