Survey Of Meteorite Samples For 92nb, 98tc, And 60fe Using Gamma Ray Spectroscopy, Robert Maxwell
Physics
The focus of this senior project was the use of gamma ray spectroscopy to survey meteorite samples for 92Nb, 98Tc, and 60Fe. The presence of measurable amounts of 26Al (half-life 717,000 years) in meteorites leads astrophysists to believe that 92Nb, 98Tc, and 60Fe should also be present in detectable amounts, though they have not yet been conclusively found. Since the isotopes that were looked for in this senior project are not long lived in comparison to the age of the solar system, their presumed presence indicates that they are continuously being made in outer space and deposited on space objects.

Physics
By posing a continual stream of pertinent questions, a nonmathematical computer program can prod freshman physics students toward an analytical solution to one-dimensional kinematics problems.
