Two neutron decay of 16Be

Recently, the first example of two-neutron decay from the ground state of an unbound nucleus, $^{16}$Be, was seen. Three-body methods are ideal for exactly treating the degrees of freedom important for these decays. Using a basis expansion over hyperspherical harmonics and the hyperspherical R-matrix method, we construct a realistic model of $^{16}$Be in order to investigate its decay mode and the role of the two-neutron interaction. The neutron-$^{14}$Be interaction is constrained using shell model predictions. We obtain a ground state for $^{16}$Be that is over-bound by approximately 1 MeV with a width of approximately 0.23 MeV. This suggests, that for such systems, the three-body force needs to be repulsive.Comment: 4 pages, 1 figure, contribution to the proceedings for the 21st International Conference on Few Body Problems in Physics, Chicago, Illinois, US

The Five-Pillar Methodology: A Crucial Approach for a Successful Community Service Project

The five-pillar methodology has been applied in the community service project Gonçalinho in Brazil. This paper provides an extension and guidelines on how to apply our methodology as a foundation for a successful general community service project. Further advice regarding step-by-step approach will be provided. Behind the five-pillar methodology, a central point related to education as a foundation and lessons learned for life will be pointed out. Important aspects regarding challenges, strategies and future trends will be addressed. Finally, additional examples based on a real community service project will be highlighted
