Abstract
Electric quadrupole transition strengths for the 2 +1 ,T=1→0 +1 ,T=1γ-decay branches are summarized for 10≦A≦42 nuclei. In10B the corresponding branch has been remeasured by use of the9Be(p, γ)10B resonance reaction atE p =320 keV; an upper limit of 0.6% is found. The variation of theE2 strengths within each individualT=1 isobaric multiplet reveals the particleor hole-character of the levels involved. The isoscalar 2 +1 →0 +1 transition strengths in 10≦A≦48 nuclei vary between 2 and 20 Weißkopf units showing drastic shell effects. Results for the ratio of neutron and proton matrix elements deduced from analogγ-decay studies and from inelastic pion scattering are compared.
