Computer program calculates the effective temperature for a crystalline solid /DETS/
Computer program computes and prints out both the Debye and resulting effective temperatures for each Debye model-dependent average energy per vibrational mode, Debye-Waller factor, and specific heat. The program calculates by the trapezodial rule and then Simpsons rule.

Epitaxial crystalline growth upon cold substrates
By sputtering a material with a high-energy ion-beam bombardment, the molecules of the target can be dislodged and ejected for subsequent deposition on a cold substrate of the desired crystallographic type and orientation.

Computer programs for calculation of thermodynamic functions of mixing in crystalline solutions
The computer programs Beta, GEGIM, REGSOL1, REGSOL2, Matrix, and Quasi are presented. The programs are useful in various calculations for the thermodynamic functions of mixing and the activity-composition relations in rock forming minerals.

Luna 16 sample G36 - Another crystalline product of an extremely mafic magma.
Luna 16 sample G36 is a microbasalt containing skeletal olivine, plagioclase, ilmenite, and interstitial pyroxene. It apparently resulted from very rapid crystallization of a highly fractionated, totally liquid mafic magma. Although different in many details, G36 is generally similar to the ferromagnesian-rich Apollo 11 and 12 basalts. In this respect, it emphasizes the continuing problem of identifying a process on the moon which generated highly mafic magmas.

Properties of crystalline bismuth selenide and its use as a Hall effect magnetometer
Single crystals of n-type Bi2Se3 grown by the Bridgman technique are found to make excellent Hall effect magnetometers. Plots of Hall resistivity sub yx against magnetic field B to 10 tesla are linear to within 1 percent. Furthermore, the slope of the sub yx against B curve varies by about 1 percent in the region 1.1 to 35 K and by less than 20 percent in the region 1.1 to 300 K. Analysis of galvanomagnetic measurements indicate the samples have semimetallic densities of approximately 10 to the 25th power/cu cm, with two band conduction and near carrier compensation. Reflectivity measurements suggest a band gap of approximately 0.08 eV for the samples. The temperature dependence of mobility is also measured. A series of 50 direct immersions into liquid helium and liquid nitrogen demonstrate the reliability of Bi2Se3 magnetometers for cryogenic use.

ERTS-1 imagery as an aid to the definition of the geotectonic domains of the southern African crystalline shield
Portions of two geotectonic environments in South Africa have been studied on ERTS-1 imagery. It was found that the broad synoptic view provided by this imagery is ideally suited to a study of the diagnostic macro-structures, and that the different geotectonic styles are clearly recorded. ERTS-1 imagery thus allows a more accurate definition than exists at present of the contact zones and internal structures of the two domains. The importance of this investigation as an aid to gaining on insight into the relevance of plate tectonics in Precambrian times is briefly discussed.
