CHART OF SANTIAGO

The “Association of Latin American Nuclear Physics and Applications” (ALANPA) was formed in Santiago, Chile on Dec. 19, 2009, by representatives of Argentina, Brazil, Chile, Colombia, Mexico, Peru and Venezuela.

In Spanish is called “Asociación Latino Americana de Física Nuclear y Aplicaciones” ALAFNA In Portuguese is called “Associação Latino Americana de Física Nuclear e Aplicações” ALAFNA

Chairs of ALANPA: Andrés Kreiner (Argentina) Alinka Lépine-Szily (Brazil)

Objectives of ALANPA (ALAFNA) To strengthen ties among the Latin American

Communities doing nuclear research and applications to foster collaborations and promotion of activities,

To educate the scientific community and the general public through the promotion of nuclear physics and the peaceful uses of nuclear technology,

To do periodic overall assessments of nuclear science in Latin America in the context of world wide activities, and

To discuss at a multi-national level future planning of nuclear science activities in Latin America

Page 5: Apresentação do PowerPoint

Role of the Steering Committee:

-establishment of ALANPA governance rules

-divulgation of ALANPA in the scientific community

-divulgation of ALANPA within governments of Latin America with interest in nuclear science and applications

ALANPA homepage will be installed in the very near futureon the website of the next “Latin American Symposium on Nuclear Physics and Applications” july 18-22,2011, Quito, Ecuador

1.1 Research Programs

The main experimental and theoretical research lines related to Nuclear Physics and its applications are the following:

• Low-energy nuclear physics: Nuclear structure, nuclear reactions, collective nuclear excitations and giant resonances, break-up reactions and their influence on fusion reactions involving weakly bound nuclei; fusion barrier distributions.

• High-energy nuclear physics: Hadronic models based on QCD. Phase structure of strong interactions.

Física nuclear y aplicaciones en el Perú

El Instituto Peruano de Energía Nuclear (IPEN) cuenta con un reactor de investigación de 10 MW, en el cual se produce radioisótopos para medicina y se realiza análisis químicos por activación neutrónica. Se tiene también una facilidad de neutrografía. El IPEN en colaboración con la Universidad Nacional de Ingeniería se realiza simulación de experimentos de fisión y experimentos de física de reactores.

Un grupo de la Pontifica Universidad Católica del Perú trabaja en el experimento ALICE con el grupo de México en el CERN.

Conclusions:

Most countries in the region have small activity in basic Nuclear Physics research. Mostly radiation and medical applications. Very small number of scientists.

Exceptions: Argentina, Brazil, Mexico

Region has no large scale facilities in NP and no plans.

Small support from funding agencies even for maintenance of existing facilities.
