Specific Heats of Rubidium and Cesium between 1.3 and 12°K

Abstract

The specific heats of rubidium and cesium were measured between 1.3° and 12°K, and Debye ⊖ values for the two metals were calculated from the data. Each metal exhibited a maximum and a minimum ⊖ value in this temperature range. In the case of rubidium the minimum ⊖ was 50 deg at 3.3°K and the maximum ⊖ was 56 deg at 9°K. For cesium the minimum ⊖ was 36 deg at 2.0°K and the maximum ⊖ was 45 deg at 9°K.
