	~~While the triple-alpha process only requires [[helium]], once some [[carbon]] is present, other reactions that consume helium are possible:~~

	~~:<math>\mathrm{_6^{12}C} + \mathrm{_2^4He} \rightarrow \mathrm{_{8}^{16}O} + \gamma + Q</math>, Q = 7.16 МeV~~

	~~:<math>\mathrm{_{14}^{28}Si} + \mathrm{_2^4He} \rightarrow \mathrm{_{16}^{32}S} + \gamma + Q</math>, Q = 6~~.~~95 МeV~~

	~~:<math>\mathrm{_{16}^{32}S} + \mathrm{_2^4He} \rightarrow \mathrm{_{18}^{36}Ar} + \gamma</math>~~

	~~:<math>\mathrm{_{18}^{36}Ar} + \mathrm{_2^4He} \rightarrow \mathrm{_{20}^{40}Ca} + \gamma</math>~~

	~~:<math>\mathrm{_{20}^{40}Ca} + \mathrm{_2^4He} \rightarrow \mathrm{_{22}^{44}Ti} + \gamma</math>~~

	:<~~math~~>~~\mathrm{_{22}^{44}Ti} + \mathrm{_2^4He} \rightarrow \mathrm{_{24}^{48}Cr} + \gamma</math>~~

	~~:<math>\mathrm{_{24}^{48}Cr} + \mathrm{_2^4He} \rightarrow \mathrm{_{26}^{52}Fe} + \gamma</math>~~

	~~:<math>\mathrm{_{26}^{52}Fe} + \mathrm{_2^4He} \rightarrow \mathrm{_{28}^{56}Ni} + \gamma</math>~~

	~~:<math>\mathrm{_{28}^{56}Ni} + \mathrm{_2^4He} + \gamma \rightarrow \mathrm{_{30}^{60}Zn}</math> (energy is consumed and the star~~'~~s core collapses)~~

	~~All these reactions have a very low rate and therefore do not contribute significantly to the energy production~~ in ~~stars;~~
	~~with elements heavier than [[neon]] ([[atomic number]] > 10) they occur even less easily due to the increasing [[Coulomb barrier]].~~

	'''Alpha process elements''' (or '''alpha elements''') are so-called since their most abundant isotopes are integer multiples of four, the mass of the helium nucleus (the [[alpha particle]]). Alpha elements are [[Atomic number\|Z]] ≤ 22: ([[Carbon\|C]], [[Nitrogen\|N]]), [[Oxygen\|O]], [[Neon\|Ne]], [[Magnesium\|Mg]], [[Silicon\|Si]], [[Sulfur\|S]], [[Argon\|Ar]], [[Calcium\|Ca]], [[Titanium\|Ti]]. They are synthesized by alpha-capture prior to the [[Silicon burning process\|silicon fusing]] process, ~~a precursor to [[Type II supernova]]e. Silicon~~ and ~~calcium are purely alpha process elements~~. Magnesium can be burned by proton capture reactions. As for oxygen, some authors{{Which?\|date=January 2011}} consider it an alpha element, while others do not. Oxygen is surely an alpha element in low [[metallicity]] [[population II star]]s. It is produced in Type II supernovae and ~~its enhancement is well correlated with an enhancement of other alpha process elements~~. ~~Sometimes Carbon and Nitrogen are considered alpha process elements, since they are synthesized in nuclear alpha-capture reactions.~~

	~~The abundance of alpha elements in stars is usually expressed in a logarithmic manner:~~
	:<~~math~~> ~~[\alpha/Fe] = \log_{10}{\left(\frac{N_{\alpha}}{N_{Fe}}\right)_{Star}} - \log_{10}{\left(\frac{N_{\alpha}}{N_{Fe}}\right)_{Sun}}~~ <~~/math~~>,
	Here <math>N_{\alpha}</math> and <math>N_{Fe}</math> are the number of alpha element and Iron nuclei per unit volume. Theoretical [[Galaxy formation and evolution\|galactic evolution]] models predict that early in the universe there were more alpha elements relative to Iron. Type II supernovae mainly synthesize oxygen and the alpha-elements (Ne, Mg, Si, S, Ar, Ca and Ti) while
	~~[[Type Ia supernova]]e produce elements of the [[iron peak]] ([[Vanadium\|V]], [[Chromium\|Cr]], [[Manganese\|Mn]], [[Iron\|Fe]], [[Cobalt\|Co]] and [[Nickel\|Ni]]).~~
