The Correspondence Between Leaky-Box and Diffusion Models of Cosmic-Ray Propagation
Ramanath Cowsik, Dawson Huth
The leaky-box model and the attendant concept of path-length distribution of cosmic rays were invented in the mid-1960's. Even though versatile computational packages such as GALPR…

A Minimal Model for Understanding Secondary Cosmic Rays
Ramanath Cowsik, Dawson Huth
We take a phenomenological approach in a minimal model to understand the spectral intensity of secondary cosmic-ray particles like positrons, antiprotons, Lithium, Beryllium and Bo…

Mapping the AMS-02 and CALET Data onto the Source Spectra and Residence Times of Galactic Cosmic Rays
Ramanath Cowsik, Dawson Huth
The recent measurements of the spectral intensities of cosmic-ray nuclei have suggested that the ratio of Boron to Carbon nuclei, , comprises two components, which c…
