Nonlinear electron dynamics in metal clusters

The intensity interferometry technique, commonly referred to as the Hanbury-Brown/Twiss effect, has been applied to nuclear and elementary-particle collisions as a method of investigating their space-time evolution. In this review the theoretical framework of the technique is presented, describing the formulations in common use. A survey is made of its application to subatomic collisions, ranging from high-energy elementary-particle reactions to low-energy nuclear reactions. Results derived from experimental data analysis are compiled and discussed. A critique is made of the interpretational difficulties associated with the use of the technique in reaction studies.

Multifragment Emission in the Reaction 36Ar + 197Au at E/A = 35, 50, 80, and 110 MeV

Intermediate mass fragment (IMF: 3{le}{ital Z}{le}20) emission for the {sup 36}Ar+{sup 197}Au reaction at {ital E}/{ital A}=35 MeV has been studied with a low-threshold 4{pi} charged-particle detector array covering the angular range of 16{degree}{le}{theta}{sub lab}{le}160{degree}. While most IMF's are emitted in central collisions characterized by large charged-particle multiplicities, contributions from peripheral collisions exist at forward angles which are reminiscent of damped collisions or emission from a projectile-like source. Energy spectra, angular distributions, element distributions, and two-fragment correlation functions are presented for various gates on the charged-particle multiplicity, and the time scale of fragment emission is deduced.

Impact Parameter Filters for 36Ar + 197Au Collisions at E/A = 50, 80 and 110 MeV

Two-fragment (Be-Be, B-B, and C-C) correlation functions were measured at small relative momenta for noncompound fragment emission in $^{36}\mathrm{Ar}$${+}^{197}$Au collisions at E/A=35 MeV. Interpretation of the experimental correlation functions in terms of final-state Coulomb-interaction models indicate average fragment-emission times of about 100--200 fm/c.

Time scale for emission of intermediate-mass fragments in 36Ar+197Au collisions at E/A=35 MeV.

The relative populations of particle-unstable states of intermediate-mass fragments were measured for the $^{14}\mathrm{N}$+Ag reaction at E/A=35 MeV with a position-sensitive hodoscope. These measurements were compared to the predictions of statistical calculations which include the sequential decay of heavier particle unstable nuclei. The best overall agreement between the calculated and measured excited-state populations was obtained with calculations which assume emission temperatures of about 3--4 MeV for the primary distributions of the particle unstable intermediate-mass fragments. However, a detailed comparison between calculated and measured excited state populations assuming ${\mathit{T}}_{\mathrm{em}}$=4 MeV reveals significant discrepancies for about one-third to one-half of the measured quantities. Calculations that include rotational effects do not satisfactorily account for this discrepancy. These results suggest the possibility of a breakdown in the assumption of local thermal equilibrium at freezeout.
