Abstract : A search for solar neutrons is reported from a balloon flight launched from Palestine, Texas on September 26, 1971. The sun was observed from 8:30 to 19:30 CST. The neutrons were detected with a telescope consisting of two 0.5 sq. m. scintillation detectors spaced 1 meter apart using a double scattering-time of flight technique. Upper limits for solar neutrons in the energy intervals 10-30, 30-50, and 50-100 MeV are 1.1 x 10 to the minus 4th power, 2.6 x 10 to the minus 4th power and 5.9 x 10 to the minus 4th power neutrons/sq. cm.-sec respectively. These are combined into an overall upper limit of 5.1 x 10 to the minus 4th power neutrons/sq. cm.-sec. (Author)
