摘要:

The relatively new type of charged particle detector known as the semiconductor detector has revolutionized the counting procedures in the field of low-energy nuclear physics. Its good resolution properties, coupled with its ease of operation, make it a natural to use in an undergraduate physics laboratory. In this paper several rather basic experiments are outlined with the use of these detectors. An alpha experiment is presented which gives the basic concepts of resolution and calibration with charged particle detection systems. Next, an alpha-decay scheme is analyzed with the corresponding gamma spectrum from the source. A(dE/dx)experiment is presented illustrating alpha particle energy loss in thin metallic foils and air. Finally an alpha-x-ray coincidence experiment is performed in both the usual coincidence manner and with a time-to-pulse-height converter. With the latter method the time distribution of the coincidence pulses is also measured.

摘要:

A simple version of the Stern-Gerlach experiment on space quantization of atomic angular momentum, utilizing a potassium atomic beam and a movable “hot-wire” detector, has been developed. A vacuum system of Corning glass pipe simplifies construction and displays the operation of the device. A general description of the apparatus is given, as is performance data and information on its use in undergraduate laboratories. A detailed construction and use manual, including shop drawings, is available from the University.

摘要:

Under different methods of representation, a spectral curve takes on different shapes. It is possible that the peak of a spectrum is found at different periods in different representations. The significance of the spectral peak is discussed.
