Cloud chamber studies of the scattering of 14.1 MeV neutrons in nitrogen, helium, and hydrogen
The nature of the interaction between a neutron and an atomic nucleus depends upon the characteristics of the nucleus involved. Consequently some information concerning nuclear structure can be derived from studies of the ...
The formation of hydrogen peroxide in water by ionizing radiation
The free radical theory of the indirect action of radiation, though not completely satisfactory, has survived nearly 10 years since it was postulated by Weiss in 1944. The suggested mechanism is as follows: (1) The primary ...
Absolute magnetic analysis of the alpha particles from polonium
The present state of the theoretical treatment of the field of nuclear phenomena, and in particular the basic subject of nuclear forces, is rather unsatisfactory. It appears quite probable that this subject will undergo ...
A study of the secondary particles of cosmic-ray penetrating showers at 3250 meters
Abstract Not Available.
Ultrasonic velocity measurements on potassium chrome alum
The velocity of propagation of longitudinal sound waves in a single crystal of potassium chrome alum was measured as a function of temperature. The waves were propagated normal to the (1,1,1) plane. In the temperature ...
Gamma radiation from certain nuclear reactions
A study of the emission of gamma rays from excited nuclei is an important means to the identification of the nuclear levels involved. By observations of cascade versus single transitions and the relative probabilities of ...
Some flow properties of liquid helium II
The properties of pressure-induced flow of liquid helium II have been studied by the observation of the temperature and pressure dependence of the flow in narrow channels. The channels are in the form of an annular slit ...
