The 63, 65Cu(3He, d)64, 66Zn reactions

Spectroscopic information from the63Cu(p, γ)64Zn reaction in the GDR region

“…3 we present the 59 results of calculations for spins of 2 + (2.994MeV) and of 4 + (3.086 MeV). Spectroscopic factors obtained in the present work from (p, 7) experiments are compared to those ones derived from the (3He, d) reaction [20] (Fig. 4).…”

“…This encouraged us to some confidence in the results of the fitting procedure also in the case of higher excited states of 64Zn where the available data are rather modest and experimental data points lie only on the lower slope of the GDR, where both the CN and DSD processes Occur. Using the same set of parameters as in the case of the ground state we obtained the spectroscopic factors of excited states given in Table 2 together with those from [20]. As the ground state spectro- Fig.…”

“…4. Comparison of spectroscopic factors obtained fi'om the present experiment with those from the (3He, d) reaction [20] scopic factor was taken from a previous work (C2S0 =1.43, [20]), all the spectroscopic factors for the excited states are "normalized" to that for the ground state, to which the symmetry optical potential, V1, was adjusted. We estimate the uncertainties of the so obtained spectroscopic factors to about 40%, most of which (~25 %) originates from C2So .…”

“…In these calculations we treated V 1 as a free parameter to obtain the best fit to the experimental excitation function for the ground state, the spectroscopic strength of which was taken from the (3He, d) reaction [20]. V 1 =50 MeV, adjusted in this way was used in further calculations to get the best fit to all other excitation functions in order to obtain spectroscopic factors of the corresponding final states.…”

Low Spin States in64Zn and66Zn

“…The (a, ny) reaction has also been used to study low spin states in 64Zn [lo, 111. The low spin states have also been studied with several other reactions [12][13][14][15][16][17][18][19][20][21][22][23] and from P'-decay of @,66Ga [24-271 .…”
