Recent breakthroughs achieved by an international team at GSI/FAIR's Experimental Storage Ring in Darmstadt, Germany, have provided essential data on the solar neutrino cross-section necessary for LOREX.

These recent measurements at GSI/FAIR's Experimental Storage Ring have significantly advanced the understanding of solar neutrino interactions.

Professors Gabriel Martinez-Pinedo and Thomas Neff highlighted the importance of nuclear astrophysics in addressing fundamental questions about the universe through this experiment.

Dr. Ragandeep Singh Sidhu emphasized that this measurement could address key questions regarding the Sun's evolution, marking a milestone in solar history research.

The publication of these findings acknowledges the contributions of late colleagues integral to the project's success, underscoring the collaborative nature of scientific research.

The Sun generates energy through nuclear fusion and emits neutrinos, which provide critical insights into its dynamics.

The LORandite EXperiment (LOREX), proposed in the 1980s, is the only long-term geochemical solar neutrino experiment currently active, aiming to measure solar neutrino flux over approximately four million years.

LOREX focuses on investigating the Sun's stability over millions of years by studying solar neutrino interactions with thallium, specifically measuring the solar neutrino cross-section.

Due to the challenges of directly measuring the neutrino cross-section on 205Tl, researchers have instead derived the necessary nuclear physics quantity through bound-state beta decay rates.

The team successfully measured the half-life of fully ionized 205Tl81+ to be 291 (+33/-27) days, a critical measurement for determining the solar neutrino capture cross-section.

When neutrinos interact with thallium in lorandite ore, they convert it into lead isotope 205Pb, which has a long half-life of 17 million years, making it suitable for the project's timeline.

With the data collected, LOREX can analyze the concentration of 205Pb in lorandite minerals, providing insights into the Sun's history and its influence on Earth's climate over millennia.
