Mechanism of the ^3^1P(p, γ)^3^2S reaction in the giant dipole resonance region |
| abstract |
The radiative capture of protons by ^3^1P has been studied in the energy range E"p" "=" "9"."5"-"1"1"."5 MeV and the gamma rays to the ground and first excited states of ^3^2S were analysed. Excitation functions and angular distributions were measured in energy steps of 20 keV. It was found that the angular distributions are almost invariant with energy and are slightly forward peaked indicating an E2 intensity of order one per cent. From the Legendre polynomial coefficient A"2A"0 the channel spin s = 0 and s = 1 fractions of the cross section were separated for ground state gamma rays; it is observed that s = 0 accounts for ~ 75 % of the γ"0 integrated strength.There are large variations in gamma-ray yield as a function of energy and an analysis in terms of statistical fluctuation theory shows that ~ 90 % of the cross section is due to a ''direct interaction'' mechanism. A large correlation between the γ"0 and γ"1 yields is observed. |

Excitation functions and angular distributions were measured in energy steps of 20 keV. It was found that the angular distributions are almost invariant with energy and are slightly forward peaked indicating an E2 intensity of order one per cent. From the Legendre polynomial coefficient A"2A"0 the channel spin s = 0 and s = 1 fractions of the cross section were separated for ground state gamma rays; it is observed that s = 0 accounts for ~ 75 % of the γ"0 integrated strength.There are large variations in gamma-ray yield as a function of energy and an analysis in terms of statistical fluctuation theory shows that ~ 90 % of the cross section is due to a ''direct interaction'' mechanism. A large correlation between the γ"0 and γ"1 yields is observed.</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">Mason, W.M.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tanner, N.W.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kernel, G.</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">138(1969), 2, Seite 253-272</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:138</subfield><subfield code="g">year:1969</subfield><subfield code="g">number:2</subfield><subfield code="g">pages:253-272</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0375-9474(69)90335-2</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">138</subfield><subfield code="j">1969</subfield><subfield code="e">2</subfield><subfield code="h">253-272</subfield></datafield></record></collection>
