Document issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Crawford Martin, regarding a legal question submitted for clarification; Who serves as District Attorney of the 16th Judicial District, pursuant to Senate Bill 906, Acts 62nd Leg., R.S., 1971.

We propose an investigation of neutrino interactions in the deuterium filled 15-foot bubble chamber at NAL. A 250,000 picture run with 200 GeV protons should yield very interesting physics even with a 'bare' deuterium chamber. This addendum extends the physics discussion in the original proposal to the search for charm particles, and the study of neutral currents. A ({nu}{sub {mu}},d) bubble chamber exposure with E{sub P} = 200-300 GeV is the most promising experiment that can be done to search for the type of charm particles that are essential to Gauge theories of weak and electromagnetic interactions. This addendum updates and summarizes Proposal 151. We propose a 300,000 picture run of the 15-foot bubble chamber filled with deuterium exposed to a wide band, 2 horn, neutrino beam from protons of energy E{sub p} {ge} 300 GeV. The analysis will be based primarily on the bare bubble chamber data but will also use the EMI wherever useful. The physics purposes of the experiment include: (1) Extensive search for charmed baryons and mesons; Determination of the ratio of the total charged current cross sections {sigma}({nu},n)/{sigma}({nu},0); (3) Determination of d{sup 2}{sigma}{sup C.C.}/dxdy for ({nu},n) and ({nu},p) interactions separately; (4) Study of ({nu},n) and …
