Since the masses of $^4{\\rm He}$ and $^4{\\rm Li}$ are almost equal, the yield of $^4{\\rm Li}$ predicted by the thermal model is 5 times bigger than that of $^4{\\rm He}$ which reflects the different numbers of internal degrees of freedom of the two nuclides. Their internal structure is, however, very different: the alpha particle is well bound and compact while $^4{\\rm Li}$ is weakly bound and loose.
