The emission of low energy, 1 A –6 A MeV, medium size, Z =3–12, fragments in 16 O + 27 Al reactions at 94 A MeV has been studied. In addition to a fragmentation component with ∼ 15 A MeV/ c parallel- and transverse momentum shifts, another component with larger momentum width is needed to describe the results. An attempt to use the VUU prescription indicates that secondary decay from excited primary fragments is important.

We present test results on the use of thin ion implanted epitaxial Si detectors for registration of low- and medium-energy heavy fragments in nuclear reactions. A linear energy response for very low energy nuclei has been observed. A test of 10 μm + 300 μm telescopes under realistic experimental conditions for heavy ion experiments exhibits the possibilities to use these detectors for the measurements of multifragmentation products.
