    In terms of the absolute 182Hf abundance, howevever, only AGB (asymptotic giant branch) models of mass ~2 to 4 solar masses are major producers of s process 182Hf in the Galaxy, owing to the combined effect of the 13C(alpha,n)16O and 22Ne(alpha,n)Mg

    You must be new to physics.

    n stands for neutron
    alpha stands for alpha particle, which is the same as a helium-4 nucleus (but with no electrons)

    The notation 13C(alpha,n)16O is a shorthand form for the nuclear reaction 13C + α → 16O + n
