Abstract
In this Rapid Communication, we report on $\ensuremath{\alpha}$-particle emission through the nuclear breakup in the reaction $^{40}\mathrm{Ca}$ on a $^{40}\mathrm{Ca}$ target at 50 A MeV. It is observed that, similar to nucleons, $\ensuremath{\alpha}$ particles can be emitted to the continuum with very specific angular distribution during the reaction. The $\ensuremath{\alpha}$-particle properties seem to be compatible with an $\ensuremath{\alpha}$ cluster in the daughter nucleus that is perturbed and is emitted by the short-range nuclear attraction of the collision partner. A time-dependent theory that describes the $\ensuremath{\alpha}$-particle wave-function evolution is able to qualitatively reproduce the observed angular distribution. This mechanism offers new possibilities for studying $\ensuremath{\alpha}$-particle properties in the nuclear medium.
