Investigations performed by the ALADiN Collaboration about signals for a liquid-gas phase transition in nuclear matter are reported. Temperature-excitation energy correlation measurements on several systems at different incident energies are compared. Moreover the comparison between isotope and excited states temperatures, extracted from double ratios of isotope yields and population ratios of fragment unbound states, respectively, shows a discrepancy between the two methods that cannot be accounted for by the sequential feeding corrections. Instead, they seem to be related to the space-time evolution of the fragmentation process. © 2000 American Institute of Physics.

    Excited states in the deformed nucleus 168Er have been studied with high energy resolution in the ( p, t) reaction, with the Munich Q3D spectrograph. A large number of excited 0+ states (25) and 2+ states (64) have been assigned up to 4.0-MeV excitation energy. This allows detailed...

  • The low-energy limit of validity of the intranuclear cascade model. Cugnon, J.; Henrotte, P. // European Physical Journal A -- Hadrons & Nuclei;Mar2003, Vol. 16 Issue 3, p393 

    The intranuclear cascade model is generally considered to be valid when the incident particle has a sufficiently small de Broglie wavelength to interact with individual nucleons. On this basis, a lower limit of 200 MeV is usually quoted for the incident energy in nucleon-induced reactions. Here...

    Branching ratios and half-lives of $ \alpha$ -decay to the ground-state rotational bands as well as the high-lying excited states of even-even nuclei have been calculated in the framework of the generalized liquid drop model (GLDM) and Royer’s formula that we improved very recently. The...
