Abstract

Strong signals of energetic neutrons associated with the solar flare of 7 September 2005 were detected by using the Solar Neutron Telescopes (SNTs) located at Mt. Chacaltaya in Bolivia and Mt. Sierra Negra in Mexico, Neutron Monitors (NMs) located at Mt. Chacartaya and Mexico City. In a previous work, the observed profiles indicate a continuous emission of neutrons. In this paper, we present the results of a unique analysis of the SNT data to obtain energy spectrum of the neutrons. The SNT channels of different response functions in energy enabled us to obtain spectrum without any assumption of the emission time profile. The result is consistent with the previous and independent studies, which indicate a differential power law index of 3. This supports the previous conclusions that the emission of the neutrons and -rays started at the same time and neutrons were continuously emitted. A marginal inconsistency about the existence of a spectral cutoff at around 500MeV may indicates some more complicated scenario.
