Determination of the mass excess of 73,75Ga, 69Cu and 79,81, as with the (d, 3He) reaction

Mass excesses of60, 62Fe,68Ni,69Cu,74Zn,73, 75Ga

“…The value found in the present experiment from the 74Ge(d, 3He)VaGa reaction is -69,709+13 keV, identical to our earlier published result [4]. The only other recent measurement is by Rotbard et al [21] who used the same reaction and determined a M.E.…”

“…(74Zn)= --65,735_+21 keV, identical to our earlier value [4]. The result disagrees with the conference report of Bernas et al [20] (M.E.=-65,570_+40 keV) who used the 76Ge(14C, 160)74Zn reaction.…”

“…We are reporting here a collection of mass excess values that have been measured at Heidelberg over the last few years with the Q3D magnetic spectrograph and MP-tandem. These mass values have for the most part only been previously reported in preliminary form in conference proceedings [4], MPIKernphysik annual reports or students' dissertations [5]. In two cases, 62Fe and 68Ni, we have more recent analyzed mass values than we previously reported [6].…”

“…The present result for the mass excess value of 69Cu was first published as a conference report [4] in 1978, M.E.=-65,734• keV, using the 7~ 3He)69Cu reaction. Since then two other values have been reported.…”
