[astro-ph.SR] Despite its low cosmic abundance, phosphorus is a bioessential element whose prebiotic availability and incorporation into biomolecules remain open questions. Only a few phosphorous containing molecules with P to […]
![Absolute CSs for the reaction of P+ with C2H2, measured at ECM = 0.14 eV as a function of the photon energy. Products are detected at m/z 56 (HCCP+, orange triangles) and m/z 55 (CCP+, blue circles). From Ephot ≈23 eV an additional product is observed at m/z 26 (C2H2 +, black squares). The vertical dashed black line indicates Ephot value at which CS trends as a function of ECM have been measured. Grey and red arrows indicate the calculated thermodynamic thresholds for production of P+ in ground and excited states, as detailed in the text.-- [astro-ph.SR]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/Synthesis.png?resize=1200%2C717&ssl=1)
