Nuclear Excitation Functions and Thick-Target Yields:Zn+dandAr40(d,α)

Radiochemical techniques have been used to determine partial or complete excitation functions to 15 MeV for the reactions ${\mathrm{Ar}}^{40}(d,\alpha ){\mathrm{Cl}}^{38}$, ${\mathrm{Zn}}^{66}(d,\alpha ){\mathrm{Cu}}^{64}$, ${\mathrm{Zn}}^{64}(d,\alpha n){\mathrm{Cu}}^{61}$, ${\mathrm{Zn}}^{67}(d,\alpha n){\mathrm{Cu}}^{64}$, ${\mathrm{Zn}}^{64}\mathrm{}(d,2p)\mathrm{}{\mathrm{Cu}}^{64}$, and ${\mathrm{Zn}}^{67}\mathrm{}(d,2p)\mathrm{}{\mathrm{Cu}}^{67}$. The results have been compared with the predictions of the statistical model of nuclear reactions. Most features of the ($d,\alpha$) and ($d,\alpha n$) excitation functions measured are consistent with the predictions of the model. The ${\mathrm{Zn}}^{67}\mathrm{}(d,2p)\mathrm{}{\mathrm{Cu}}^{67}$ reaction appears to take place essentially by a direct process, while the ${\mathrm{Zn}}^{64}\mathrm{}(d,2p)\mathrm{}{\mathrm{Cu}}^{64}$ reaction, which has a much higher cross section, agrees with the model. Support is found for a rather large value of the nuclear radius parameter, $r_0=1.7\mathrm{}$ F. Excitation functions are presented for the reactions ${\mathrm{Zn}}^{64}\mathrm{}(d,p)\mathrm{}{\mathrm{Zn}}^{65}+{\mathrm{Zn}}^{64}\mathrm{}(d,n)\mathrm{}{\mathrm{Ga}}^{65}\left({\beta }^{+}\right){\mathrm{Zn}}^{65}$, ${\mathrm{Zn}}^{66}\mathrm{}(d,n)\mathrm{}{\mathrm{Ga}}^{67}$, and ${\mathrm{Zn}}^{66}\mathrm{}(d,2n)\mathrm{}{\mathrm{Ga}}^{66}$. Thick-target yields from deuteron bombardment of metallic zinc are given for ${\mathrm{Cu}}^{61}$, ${\mathrm{Cu}}^{64}$, ${\mathrm{Cu}}^{67}$, ${\mathrm{Zn}}^{65}$, ${\mathrm{Ga}}^{66}$, and ${\mathrm{Ga}}^{67}$.
