Assessment of 53Mn deposition on Earth via accelerator mass spectrometry
The 53Mn flux onto Earth is a quantity relevant for different extraterrestrial and astrophysical questions. It is a proxy for related fluxes, such as supernova-produced material or interplanetary dust particles. In this work, we performed a first attempt to assess the 53Mn flux by measuring the 53Mn...

It is a proxy for related fluxes, such as supernova-produced material or interplanetary dust particles.
