Partial coherence in heavy-ion reactions
First- and second-order interferences are investigated for fluctuating cross sections with average angular distributions <dσ/dΩ> not necessarily symmetric about 90^o. This is expected to be relevant for reactions between light complex nuclei where discrete final states are populated through an...

Partial coherence in heavy-ion reactions |
| abstract |
First- and second-order interferences are investigated for fluctuating cross sections with average angular distributions <dσ/dΩ> not necessarily symmetric about 90^o. This is expected to be relevant for reactions between light complex nuclei where discrete final states are populated through an intermediate deep-inelastic or precompound process. We obtain <dσ/dΩ> as a sum of coherent and incoherent contributions from either side of the interaction region. The period of the oscillations present in <dσ/dΩ> as well as in the angular cross-correlation function is determined by a characteristic angular momentum Λ. while the damping of these oscillations depends on two angular momentum widths Δ and δ, which characterize the range of contributing partial waves and their phase correlation length, respectively. Using gaussian distributions simple formulae are derived by means of which the quantities Λ, Δ and δ may be extracted directly from the data. In the limit δ = 0 we obtain a transparent description of heavy-ion compound reactions. The excitation function exhibits gross structure whose period is determined by Λ(E). |

This is expected to be relevant for reactions between light complex nuclei where discrete final states are populated through an intermediate deep-inelastic or precompound process. We obtain <dσ/dΩ> as a sum of coherent and incoherent contributions from either side of the interaction region. The period of the oscillations present in <dσ/dΩ> as well as in the angular cross-correlation function is determined by a characteristic angular momentum Λ. while the damping of these oscillations depends on two angular momentum widths Δ and δ, which characterize the range of contributing partial waves and their phase correlation length, respectively. Using gaussian distributions simple formulae are derived by means of which the quantities Λ, Δ and δ may be extracted directly from the data. In the limit δ = 0 we obtain a transparent description of heavy-ion compound reactions. The excitation function exhibits gross structure whose period is determined by Λ(E).</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hartmann, K.M.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Dunnweber, W.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Frahn, W.E.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Nuclear Physics, Section A</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">380(1982), 1, Seite 170-188</subfield><subfield code="w">(DE-627)NLEJ177217928</subfield><subfield code="w">(DE-600)1466542-6</subfield><subfield code="x">0375-9474</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:380</subfield><subfield code="g">year:1982</subfield><subfield code="g">number:1</subfield><subfield code="g">pages:170-188</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0375-9474(82)90588-7</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">380</subfield><subfield code="j">1982</subfield><subfield code="e">1</subfield><subfield code="h">170-188</subfield></datafield></record></collection>
