- The Role of Standard Reference Materials in Measurement Systems
- Report is a guide to Standard Reference Materials (SRM's) and should be useful to all users of SRM's particularly those in countries developing national measurement systems. It is not intended to be an exhaustive description of the NBS-SRM program, but rather a review of the role SRM's play in the measurement system, how SRM's are certified, and what the certification means. To illustrate the use of SRM's, several selected industries are described in which SRM's have made significant contributions. digital.library.unt.edu/ark:/67531/metadc70416/
- Analysis of Optically Excited Mercury Molecules
- Report presenting new measurement techniques used to obtain potential curves, f-values, and kinetic behavior for Hg2. The Hg2 molecule is representative of a class of molecules which have dissociative ground states and bound excited states. It can therefore be used as a prototype of this class of molecules which are of interest as potential new laser candidates. Because of the non-bound ground state, standard absorption spectroscopic techniques cannot be used to obtain the necessary information about the excited states. digital.library.unt.edu/ark:/67531/metadc70413/
- Thermocouple Reference Tables Based on the IPTS-68: Reference Tables in Degrees Fahrenheit for Thermoelements versus Platinum (Pt-67)
- Report presenting tables as a supplement to those given in NBS Monograph 125. Tables were calculated from the power series expansions presented in that Monograph. They are based upon the absolute electrical units and the International Practical Temperature Scale of 1968 (IPTS-68). Reference tables for several thermoelements versus platinum (Pt-67) are given with values of the thermoelectric voltage as a function of temperature in degrees Fahrenheit. Only tables for standard letter-designated thermoelements are included. digital.library.unt.edu/ark:/67531/metadc70407/
- Interactions of High Energy Particles With Nuclei
- Report discussing elastic scattering and diffractive production processes induced in nuclear targets by high energy projectiles. Special attention is paid to the interaction of high energy hadrons and photons. The common features of all these processes are emphasized throughout the article: The multiple scattering and shadowing processes inside of the target nuclei. An effort is made to develop a unified way of treating nuclear interactions of particles which are either hadrons or exhibit some hadronic components in such interactions. digital.library.unt.edu/ark:/67531/metadc70411/
- A Gage Block Measurement Process Using Single Wavelength Interferometry
- Report describing the interferometric measurement process using a laser light source and a Kosters type gage block interferometer. Continuous evaluation and refinement of the process is aided by statistical treatment and control chart techniques. All error sources, both random and systematic, are evaluated and the process is maintained in a state of statistical control. digital.library.unt.edu/ark:/67531/metadc70418/
