Spectator Fragmentation Induced by Relativistic
ثبت نشده
چکیده
In 1998 and 1999, a series of experiments[1] was conducted at the GSI with the INDRA multidetector [2], using high-energy beams from the heavy-ion synchrotron SIS. A part of them was devoted to asymmetric systems like C+Au and C+Sn at bombarding energies ranging from 95 to 1800 AMeV. High resolution at backward angles, dominated by emissions from the target spectator, was achieved with the Si-Si-CsI(Tl) calibration telescopes of INDRA. The physics goals in this study of spectator fragmentation are the principal question of thermal and/or dynamical breakup of the source, and, with the isotopically pure tin targets, the role of the isospin degree of freedom in the fragmentation process.

Spectator-model operators in point-form relativistic quantum mechanics
We address the construction of transition operators for electromagnetic, weak, and hadronic reactions of relativistic few-quark systems along the spectator model. While the problem is of relevance for all forms of relativistic quantum mechanics, we specifically adhere to the point form, since it preserves the spectator character of the corresponding transition operators in any reference frame. ...

Hypernuclear physics is a useful tool to investigate the properties of the hyperon-nucleon (Y N ) and the hyperonhyperon (Y Y ) interaction [1]. The knowledge of the strangeness sector of the hadronic equation of state might be important for nuclear astrophysics, e.g., for the properties of neutron stars [2], and in exploring exotic states of finite nuclei, e.g., neutron-rich strange nuclei and...
متن کاملDynamical aspects of isotopic scaling
Investigation of the effect of dynamical stage established that the increasing width of initial Gaussian distributions is reflected by significant modification of the slope of final isoscaling plots after deexcitation. For narrow initial Gaussian distributions, the slope of isoscaling plots assumes the limiting value for two individual initial nuclei while for wide initial Gaussian distribution...

Recent theoretical work [1] suggested the longitudinal velocities of the fragmentation residues produced in relativistic heavy-ion collisions as an observable sensitive to the momentum dependent (MD) properties of the nuclear mean field (MF). Under certain conditions, the spectator remnant can acquire on average even a positive momentum during the collision This phenomenon has been named specta...
متن کاملIsoscaling in spectator fragmentation at relativistic energies
The phenomenon of isoscaling is receiving considerable interest because of its relation with the symmetry term in statistical [1] and dynamical [2] descriptions of fragmentation reactions. As reported recently, the symmetry term coefficient γ in the liquid-drop description of the nascent fragments appears to be decreasing from the standard value γ = 25 MeV for isolated nuclei to about 15 MeV or...
