“…Tang & Anders (1988b) and Ott & Begemann (2000). Here, instead of a constant recoil range, we use a distribution based on theoretically derived energy spectra for 21 Ne (Figure 2) calculated as described in Wrobel (2008). Retention values for the individual grains are listed in Table 1.…”

Knowledge about the age of presolar grains provides important insights into Galactic chemical evolution and the dynamics of grain formation and destruction processes in the Galaxy. Determination from the abundance of cosmic ray interaction products is straightforward, but in the past has suffered from uncertainties in correcting for recoil losses of spallation products. The problem is less serious in a class of large (tens of µm) grains. We describe the correction procedure and summarise results for He and Ne ages of presolar SiC 'Jumbo' grains that range from close to zero to ∼850 Myr, with the majority being less than 200 Myr. We also discuss the possibility of extending our approach to the majority of smaller SiC grains and explore possible contributions from trapping of cosmic rays.

“…For over 60 years, the nuclear optical model (OM) has provided a means of analyzing nuclear scattering data, both to characterize the nucleon-nucleus interaction and to represent nuclear data for applications in other research and in engineering [1]. Some of the most challanging nuclei to model have been those, such as 28 Si and 32 S, with relatively low atomic number and non-spherical properties.…”

Due to cosmic rays, electronic devices such as SRAM may undergo some dysfunctions such as single event upsets also called Soft errors. A crucial issue for aerospace applications is to be able to predict the Soft Error rate of a given device in a given environment. In this work, we present a predictive tool which deals with protons and heavy ions for space applications and with neutrons for atmospheric applications. Moreover, it deals with alpha particles which can be emitted naturally within the device, during nuclear decay of polluting uranium, thorium and their daughter nuclei. Natural alpha emitters from materials, such as hafnium, are also considered. Thus, the novelty of the code is its ability to address the issues of space, avionic and ground level applications. The Monte Carlo approach allows calculating simply the single event upset and multiple bit upset cross sections as well as the associated Soft Error rates. To state whether an error occurs or not, the code is able to consider well known criterions such as the critical energy deposited in a sensitive volume or the ambipolar diffusion model.
