Exact Dirac equation calculation of ionization induced by ultrarelativistic heavy ions
نویسنده
چکیده
The time-dependent Dirac equation can be solved exactly for ionization induced by ultrarelativistic heavy ion collisions. Ionization calculations are carried out in such a framework for a number of representative ion-ion pairs. For each ion-ion pair, the computed cross section consists of two terms, a constant energy independent term and a term whose coefficient is ln γ. Scaled values of both terms are found to decrease with increasing Z of the nucleus that is ionized. PACS: 34.90.+q, 25.75.-q

An exact solution of the time-dependent Dirac equation for ionization and pair production induced by ultrarelativistic heavy ion collisions is presented. Exact transition probabilities, equivalent to those that would be obtained in an untruncated basis coupled channels calculation, are presented. Exact bound-electron positron pair production probabilities are calculated to be mostly smaller tha...

متن کاملSome exact analytical results and a semi-empirical formula for single electron ionization induced by ultrarelativistic heavy ions
The delta function gauge of the electromagnetic potential allows semiclassical formulas to be obtained for the probability of exciting a single electron out of the ground state in an ultrarelativistic heavy ion reaction. Exact formulas have been obtained in the limits of zero impact parameter and large, perturbative, impact parameter. The perturbative impact parameter result can be exploited to...
متن کاملFermion Production in Classical Fields
Here, the formalism for the production of fermion-antifermion pairs by vacuum polarisation due to classical fields is investigated according to and extending Refs.1,2. The issue of gauge invariance is discussed for the calculation of the expectation value for the number of produced pairs from the exact retarded and/or advanced propagator. These correlators are given as solutions of the equation...
متن کاملCoherent electromagnetic heavy ion reactions: (1) exact treatment of pair production and ionization; (2) mutual Coulomb dissociation
In ultrarelativistic heavy ion collisions, Coulomb induced cross sections are huge, much larger than geometric. For the RHIC case of 100 GeV × 100 GeV colliding gold ions the predicted cross section for bound-electron positron pairs is about about 110 barns[1]. The corresponding cross section for continuum electron-positron pairs has recently been recalculated to be 34,000 barns[2], consistent ...
