  • Study of the finite-temperature effects in nuclear systems remain one of the least explored subjects in low-energy nuclear physics, despite the fact that dramatic structural changes are expected to unfold as the excitation energy of the system is increased. Gradual vanishing of the pairing correlations, onset of chaos and rotational damping, prolate-to-oblate shape changes, melting of the shell effects, and eventually the inability of the compound nucleus (CN) to sustain giant resonances at very high temperatures ( death'' of CN) are only a few examples of the rich and varied phenomena yet to be explored. Equally important is the questionmore » of thermal fluctuations and the extent to which they modify the above phase transitions. However, a prerequisite to the study of these fascinating questions is a detailed understanding of the formation and decay modes of compound nucleus which is astonishingly, lacking at present. In this chapter we shall discuss some recent experimental and theoretical developments that (a) raise new questions about these pivotal issues, and (b) provide clues and directions toward their resolution. They include questions of equilibration of CN (entrance-channel effects in fusion reactions, and structural effects in evaporation-proton spectra), and variations of the gamma strength functions with spin and temperature which directly affect deexcitation of CN following particle emission.« less

  • Laser plasma interaction experiments have been perform performed using an fs Titanium Sapphire laser. Plasmas have been generated from planar PMMA targets using single laser pulses with 3.3 mJ pulse energy, 50 fs pulse duration at 800 nm wavelength. Electron density distributions of the plasmas in different delay times have been characterized by means of Nomarski Interferometry. Experimental data were cautiously compared with relevant 1D numerical simulation. Finally these results provide a first experience of searching for the time-space position of the so-called warm dense plasma in an ultra fast laser target interaction process. These experiments aim to prepare nearmore » solid-density plasmas for Thomson scattering experiments using the short wavelength free-electron laser FLASH, DESY Hamburg.« less
