However, if we still explore this:

Assuming the correct notation refers to the double beta decay of Carbon-13 to Nitrogen-13: co3 0nu

To date, no experiments have been conducted specifically targeting the 0νββ decay of 13C. The primary reason is the extremely low expected rate and high background levels anticipated in such measurements. However, if we still explore this: Assuming the

13C → 13N + 2e- (for 0νββ)

The neutrinoless double beta decay (0νββ) is a rare nuclear process in which a nucleus emits two beta particles (electrons) without emitting any neutrinos. This process is of great interest in particle physics because it can provide insight into the nature of neutrinos and the mechanism of neutrino mass generation. One of the candidates for this process is the isotope Carbon-13 (13CO3 or 13C). This process is of great interest in particle

Carbon-13 is not commonly studied for 0νββ decay due to its relatively low atomic mass and unfavorable Q-value. The more commonly studied isotopes have higher Q-values and larger nuclear matrix elements.
