Modesto Montoya (born 24 February 1949) is a nuclear physicist at the Instituto Peruano de Energía Nuclear in Lima, Peru. He is past president and a member of the Peruvian National Academy of Sciences and past president of the Peruvian Physical Society.
Academic activities
Montoya holds a BSc, a Lic. a MSc in physics from the University of Engineering, a DEA, a doctorat de 3eme cycle and a doctorat d'Etat from the Paris-Sud 11 University. He is affiliated as professor to the National University of Engineering and he teaches scientific and technological subjects at Centro de Preparación para la Ciencia y Tecnología (Ceprecyt).[1] [2]
Research
Montoya's research work was on cold fission at the CEA Saclay and he participated in the discovery of nucleon-pair breaking in cold fission,[3][4] phenomenum studied also by Hervé Nifenecker[5] in cold fission of uranium 233, uranium 235 and plutonium 239. He also studied the mass and kinetic energy distribution of fragments in cold fission[6]
Between 1985 and 1986 he was guest scientist at (GSI) in Darmstadt in the group led by Peter Armbruster, dedicated to research on transuranides nuclei.[7][8] At GSI published his work on Coulomb and shell effects in low energy fission.,[9][10]
As guest scientist at the Institut de Physique Nucléaire, Orsay, in the Bernard Borderie's group, he participated in research on deeply inelastic collisions.[11] He was also invited by the Carnegie-Mellon Institute in the Morton Kaplan group dedicated to ternary fragmentations in nuclear collisions.[12]
Montoya now studies the effects of neutron emissions on measurements of fission fragments.[13][14][15]
Promoting science and technology
Montoya has had his opinions on science and technology published in a number of articles in the main Peruvian newspapers.[16] He is also frequently interviewed by newspapers about issues connected with science and technology.[17] As part of his promotional activities he found the International Scientific Meeting (ECI) for which is recognized by international institutions.[18]
