Ammonia borane-based targets for new developments in laser-driven proton boron fusion

Nuclear fusion reactions involving protons and boron-11 nuclei are sparking increasing interest thanks to advancements in high-intensity, short-pulse laser technology. This type of reaction holds potential for a wide array of applications, from controlled nuclear fusion to radiobiology and cancer therapy. In line with this motivation, solid ammonia borane samples were developed as target material for proton-boron (pB) nuclear fusion. Following synthesis and shaping, these samples were tested for the first time in a laser-plasma pB fusion experiment. An investigation campaign focusing on surface chemical/physical analysis was carried out to characterize such samples in terms of composition of B and H, precursors of the pB fusion nuclear reaction, thus having a key impact on the yield of the generated nuclear products, i.e., alpha particles. A follow-up experiment used an 8 J, 800 fs laser pulse with an intensity of 2 x 10(19) W cm(-2) to irradiate the targets, generating similar to 10(8) alpha particles per steradian. The alpha particle energy range (2-6 MeV) and normalized yield per laser energy of up to (6 x 10(7) J/sr) are comparable with the best previous alpha particle yields found in literature. These results pave the way for a yet unexplored category of pB fusion targets

A New Way to Link Development to Institutions, Policies and Geography

The paper aims to examine the role of institutions relative to economic policy and geography in explaining the differential level of development across countries over time. To that end, it attempts to construct a Development Quality Index (DQI) and an Institutional Quality Index (IQI) by using multivariate statistical method of principal components. It shows that (i) higher level of IQI along with economic policy and geography factors lead to a positive improvement in the level of DQI; and (ii) results remain robust for IQI and relatively robust for economic policy and geography even when it is compared across cross-section and panel data estimation for a set of 102 countries over 1980 to 2004. The results strongly indicate that institutions matter in the context of specific economic policy mixes and geography related factors illustrated by disease burden, etc. It demonstrates that relative influence of institutions varies across stages of development
