Description
There are discussed two methods to distinguish the coalescence from thermal production of light nuclei. At first the hadron-deuteron correlation function is shown to carry information about an origin of deuterons, whether they are emitted from a fireball together with all other hadrons or formed due to final state interactions after nucleons left the fireball. Secondly, it is proposed to measure the yield of an exotic nuclide $^{4}$Li and compare it the yield of $^{4}$He. The coalescence and thermal models predict a significantly different ratio of the yields of $^{4}$Li to $^{4}$He. A measurement of $^{4}$Li is discussed.
